Velocity on Impact:
Pancake fall: 373mph or Mach0.49
Nosedown fall: 763mph or Mach1.03
Assumptions;
The T80U is falling pancake, ie level. The T80U impacts the ground at sea level, thus the air density can be taken at sealevel, final and probably worst assumption; the T80U is at terminal velocity at point of impact. suvat equations say that in 4000m a T80U will reach 630mph, therefore it probably can be assumed to be at terminal velocity.
Drag coefficient (Cd) of a cube; 1.05 (Brick Cd used, not just a flat cuboid but one with some surface irregularities)
Area (A) of the T80U's underside; 7m(Length) * 3.6m(Width)= 25.2m^2
Density of air at sea level (p) at 15degrees C; 1.225 kg/m3
Mass of a T80U; 46tonnes or 46000kg multiplied by acceleration under gravity (9.81m/s-2) to get Weight (W); 451260N
Net force on vehicle, F, is equal to DragForce, Fd, minus the weight
F=Fd-W
Fd=(Cd*p*V^2*A)/2 where V is velocity
F=((Cd*p*V^2*A)/2)-W
At terminal velocity, F = 0. Rearrange for V gives
V=sqrt( (2W)/(Cd*p*A))
V=166.87m/s
V=373.3mph
V=0.49mach
However, A changes to only 7.92m^2 if it's falling nosedown, and assuming an angled cube's Cd of 0.75 which gives a new Vt of 352m/s or 762.8mph; mach1.03
I looked in the comments just for this. Thank you.
For true intellectuals, pancake dive is 1075 bananas per second, and nose dive is 1919 bananas per second
V=Squirt
Now i understand that i understand nothing
@@lirokangaming6937 Basically;

The terminal velocity of any given object is determined by several factors: mass, cross-sectional area, drag coefficient, medium density, and gravitational acceleration.
Below are the notations and explanations of these variables:
Mass (m) - the quantity of matter an object has, regardless of volume or any forces acting upon it (not to be confused with weight, which is "...the measure of the force of gravity acting on a body".
Cross-sectional area (A) - the area of the object that is projected towards the fluid it is falling through. For simplicity sake, we will assume the tank is falling onto its tracks - so its A will be the surface area of the bottom of the hull.
Drag-coefficient (Cd) - a constant that represents the amount of resistance an object would have when travelling through a fluid. This is dependent on more factors such as the object's shape, texture, viscosity, compressibility, lift, boundary layer separation, and more.
Medium Density (p or "rho") - density of the fluid that the object is travelling through. Note that in air, density varies with dew point, temperature, and air pressure. However, we will assume an average air density of 0.4135 kg/m^3 at a drop altitude of 10,000 m.
Gravitational acceleration (g) - a measurement of the force of gravity acting on the object. Along with mass (m), one can calculate the object's weight (W) via W = mg.
Drag force (Df) - calculated using the drag-coefficient (Cd) to determine the force of drag that is opposing an object's motion.
--------------------------------------------------------------------------
The formula to calculate terminal velocity (Vt) is given as:
Vt = sqrt((2m*g)/(p*A*Cd)) = sqrt((2W)/(p*A*Cd)
Ideally, drag coefficients are best determined via actual experimentation. However, because our object is so heavy and blunt, we can assume its Cf is approximately 1. The weight of a combat ready T80-U battle tanks (including fuel, ammunition, and crew), is approximately 46 tons while its chassis length and overall width are 7.01 m and 3.60 m respectively, giving us a cross-sectional area of 25.236 m^2.
In summary:
W = mg = 46 mt = 46,000 kg
A = 25.362 m^2
Cd = 1
g = 9.81 m/s^2
p = 0.4135 kg/m^3
When we plug it in we get a Vt of 293.359 m/s.
Conclusion: If a combat ready T80U tank fell track first from an altitude of 10,000 m, it would impact the ground at approximately 293.359 meters per second, 962,466 feet per second, 1056.095 kilometers per hour, 656.227 miles per hour, or mach 0.855.
Crew Analysis - "knocked out" ;)
Tank Analysis - perfectly fine....because of Stalinium ;)
Hope this helps! Let me know if I messed up anywhere :)
No no no, stalinium protect crew, crew not get a scrach if they believe in glorious leader, he protect them. But now honestly, this is a great calculation, I would have doneit, but I am too lazy, soI admire you takeing time to do it. At that speed, thank would probably burst at the welds, and crew will leave a little more than a match box worth of organic mather behind them. That is if you manage to dig throughto them in the first place if you drop them somwhere with softish ground, again to lazy (sorry) to calculate the depth of impact crater.
Pretty sure Phly said 4km not 10km.
@@Tampscity Shhhh we're enjoying the thought of a T80 hitting Mach 0.86 before it experiences inertial dampening from the ground.
You won't get out, not when it dives at 300 knots.
This is true but both your cross section and air density are fucked up, especially the air density it mess up the results. the air density at sea level is roughtly 1.2 kg/m^3 and is the only one that matters as he asked about the terminal velocity on ground from 4000m not the terminal velocity at 10000m. Next as you may have seen the tank was slightly spinning so it would be much more suited to give 2 velocities, one with the tank facing the ground and one with the tank on it's tracks.
Witch gives is a terminal velocity on it's tracks of 165 m/s, or 571 km/h and 355 mph,
and a terminal velocity facing downwards of roughtly 410 m/s, or 1477 km/h and 917 mph, witch is mach 1.2 asl

We have the equation : Fd = Cd . 0,5 . p . v^2 . A
Fd = drag force (N)
Cd = drag coefficient (depends on the shape, here we'll approximate the tank as a rectangle) ~ 1,2
p = density of air = 1,225kg/m^3
v = speed (m/s)
A = frontal area of the tank ~ 20m^2
To find the terminal speed :
force of gravity on the tank = drag force on the tank at terminal speed
So :
9,81 . 46 000 = 1,2 . 0,5 . 1,225 . v^2 . 20
We find v = 175m/s
If we assume that the tank reaches his terminal speed before 4km of fall, it will hit the ground at ~630km/h

I like how the long range shots enter the tank at an angle yet the kill feed still shows it as a flat entry
it is likely due to perspective. You are looking parallel to its flight path. All you see is its vertical motion so it looks like it is really steep since you can't tell how much distance it is covering for every meter it drops.
@@neurofiedyamato8763 i'm not sure that is true
i fired extreme lobbing shells and they appear to come in flat in XRAY
+ now there's a bug with HESH
HESH shots come perpendicular to the plate you're hitting
so if you hit a downward angle on the turret , you can have the shell spawn from underneath the tank one shotting it
my use of english is rudimentary sorry :(
@@neurofiedyamato8763 is right. Your frame of reference is what skews your expectation. The round is still flying nearly perpendicular to the ground when it hits the targets and you won't see the downward entry path your expect. A good way to visualize this is to change your point of reference to the side further away and watch the round trajectory.
There is a really good real life example of this 'illusion.' Search up the Eshima Ohashi bridge in Japan. Looking down along the length of the bridge looks like it is really steep but at any other angle, it is fairly normal. You can tell that it isn't all that step based on the cars which aren't angled much, but many people looking at pictures still fall for it.
@@neurofiedyamato8763 HOLY SH*T DUDE
This was interesting as it differs from game to game, as it's usually tied to render range. WOT has a lower render range, so shells despawn after 850m so you can blind fire across the map. BF3 Mythbusters did find shells despawning after 3km. No idea if BF4 can go longer.

Without air resistance:
v = sqrt(2*9.81*4000) = 280 m/s ~ 1008 km/h
If you want to add air resistance you should subtract F_w * s from the potential energy where F_w is the force air pushes against the tank but is a function of the velocity itself squared and a constant.
v = sqrt(2*4000*(9.81 - F_w(v)/m ))

Phly, give this a shot in the stormpanzer. Hard mode :)
For the terminal speed dropping from 4000 meters, one can use energy conservation law to find the speed of it.
by energy conservation,
mgh = 1/2*mv^2,
m is the mass, g is gravitational acceleration, h is the height. v will be the speed.
so the formula can be simplified to:
gh = 1/2*v^2
g will be 9.8m/s^2, height will be 4000 meters,
so the speed will be:
v = sqrt(2*g*h) = sqrt( 2* 9.8m/s^2 * 4000m) = 280m/s
sqrt is square root.
Be aware this is the simplified model, if you want to consider the air friction, you have to have more data, eg the shape and the friction force on the material.....etc.
Phly: "How long can you shot in war thunder?"
Me: "As long as i have ammo xD "
With the right custom sights you can hit out to about 10km in RB against Ka-50's. There's a really cool sight for the M1A1 that lets you range out to 9km. Combined with the laser rangefinder if a KA-50 is hovering 8, 9 or even 10km away, you can get a 1 shot kill on him. I've done it a couple of times at 8 and 9km.
Supersonic Jets more like supersonic tanks. Sonic the Hedgehog noises Starts
Assuming the T-80U is 46 tons (War thunder wiki) falling in a "bottom-down" position, the area is about 25m(2) (Wikipedia - 7m long, 3.6m wide). Also assuming the drag coefficient is about the same of that of a brick, air density of impact point at sea level and normal gravity, *The terminal velocity would be around 110m/s*
If it would be falling in a more "nose-down" position and had a better drag coefficient, it could reach around 160-170m/s

The Mars Climate Orbiter, built at a cost of $125 million, was a 338-kilogram robotic space probe launched by NASA on December 11, 1998 to study the Martian climate, Martian atmosphere, and surface changes. In addition, its function was to act as the communications relay in the Mars Surveyor â98 program for the Mars Polar Lander. The navigation team at the Jet Propulsion Laboratory (JPL) used the metric system of millimeters and meters in its calculations, while Lockheed Martin Astronautics in Denver, Colorado, which designed and built the spacecraft, provided crucial acceleration data in the English system of inches, feet, and pounds. JPL engineers did not take into consideration that the units had been converted, i.e., the acceleration readings measured in English units of pound-seconds^2 for a metric measure of force called newton-seconds^2. In a sense, the spacecraft was lost in translation.
I guess you can shoot as long as you've got ammo.
just through some basic googling I come up with the length and width of the t-80 being about 7.4m by 3.4m
Assuming the t-80 falls flat tracks parallel to the ground), this gives us a cross-sectional area of 25.16 m^2
The T-80B weighs 42.5 tonnes according to Wikipedia, which is 42 500kg. Multiplying by 9.81 m/s^2 we get a gravitational force of 416 925N.
With it's cross-sectional area of 25.16m^2, approximating the tank as a flat rectangle, and assuming the air density is constant, the tank would have to travel 116.3 m/s to balance out the forces.
That means that assuming the tank reached the top speed during the fall (which, be honest, is pretty likely considering how long it was) it would have been traveling at 418.68 km/h (260 mph).

hi sailydaily can you play the albatros-klasse(143) boat. Im thinking about grinding for it and dont know if its worth it. if you play it have fun. thanks u
If no one Phlies ships in WT, do they really exist?
Talking about the problem at the end of the video. The Speed of the T80U falling from 4000m without air resistance is pretty easy. We got the h(hight), g(Gravitational constant 9.81) . We just need the time. Which you can get with | root of h*2 devided by g and this is exact 28.552s| for the speed we can do (because of the free fall) g*t=v and this will give us 280,143 m/s speed at the slaming point. This does not take the air resistance in consideration but I am working on that one. If the T80U would fall through a vakuum than it will gain 280 m/s.
The US patriot missile system was also broken because of the imperial/metric blunder :)
In warthunder rounds have a power and gravity arc. So rounds will run out off puff and fall to ground. But then again cannon and mg's vanish shooting straight up. Might be a question for the Shooting range to answer.
Hey phly play the M2a2 and get 10 kills attempt #70
If we had no air ressistance velocity before t80u hit the ground would be 280 m/s(1000km/h),
because i couldnt get the drag coefficient and the tank would probably spin a lot if i just used some in between values for surface area and drag coeficcient. and the velocity cam up to be
213m/s(768m/s) i guess it would be anywhere beetween 185m/s-230m/s.
Anyways enough to squash all Ivans. Also bring out the t34(1942)
Do it in game and be the most respected player in the game.
Or the most hated. Anyone who can land a shot across the rocks on Finland is considered a cheater by a slightly less than considerable bunch of cazhuls, anything more than that and with a few bushes along the way(not even blocking LoS) and an actually considerable pile of pitchfork holders will hate your guts when the guy you shot takes the cloaker's advice and goes to the forum to cry like a little bitch.

Terminal velocity in War Thunder physics
given 4000m in 24 seconds fall
=13,88 m/sÂČ gravitational acceleration (Normal would be 9,81)
=333,33 m/s velocity
So at the ground the T80 would have a Velocity of 1200 km/h
And you wouldnt have to worry about your crew as very little would remain of the tank in a very flat condition ;)
Phlydaily invents a new unit of measure: the banana.
No, the banana is a common form of measurement here in the US
That range is just Bannanas đđđđ
Sorry for the dad joke
Somebody had to do it eventually
Answer: aslong as your shoot-important things dont get destroyed
So interesting tidbit. When firing in a parabolic arc the angle at which to fire the farthest is 45 degs. However the higher you raise the shooter above the plane the lower that angle becomes. Thatâs why you had to lower the range off of 10 km to hit the target. Since the sight is set for two object at roughly the same plane
BTW METRIC SYSTEM IS THE BEST not the shitty feet and miles
Alright, so for something to reach terminal velocity it has to accelerate up to the point where the air drag equals the force of gravity, so we have here:
Drag=(p*v^2*C*A)/2
p is the density of the fluid ( air in this casse)
v is the velocity (which we want)
C is the drag coefficient, which depends on the shape of the object. And since I didn't find the correct value for a T-72, I'll use the value of a vehicle similar in shape (size or mass don't matter), so I chose the peugeot 305, which has a drag coefficient of 0.44
A is the cross sectional area. So, considering that the tank falls standing at the same position as when it's on the ground, we can multiply lenght and width to get the area.
A=9.53*3.9 (for a T-72)
D=(v^2*1.225*0.44*9.53*3.9)/2
D=10.016*v^2
ok, so this needs to be equal to the force of gravity, which is given as: F=mg
m is the mass (41.5 metric tons for a T-72)
g is the acceleration of gravity
F=9.81*41500
F=407,115 Newtons
now we equal both equations and we get
407115=10.016v^2
and the terminal velocity of a T-72 is 201.6m/s
or 725.76 km/h
or for the slower ones : 450 mph

Terminal Velocity of a T-80U *rough calculations
Mass: 46000 kg
Density of air at 25C: 1.1839 kg/m3
gravity: 9.80 m/s2
Drag coefficient (estimated): 0.59
Projected area (estimated): 6.54191 m2
Thus, the terminal velocity of a t-80u if falling barrel side down, is sqrt(2*46000*9.80/1.1839*6.54191*0.59) which is roughly 444.192 km/h
Everyone know a tank lands at its tracks. Also you can very easily estimate the terminal velocity using the formula v=gt, where g=9.8 m/s^2. If you didn't count the time you but know the height you were at, you can solve this formula for t: h=(gt^2)/2
Phly. You got mad high didn't you? Holy shit I can't stop thinking about that. All of the amazing info and everything we have ever experienced, loved, hated and everything in-between on our PCs was provided by rapidly moving electrons.
When youâre significantly above a target you need to shoot just below a target most of the time to account for the arc of the ballistic.
24 seconds drop, and the Earth's gravitational acceleration of 9.8, give us a a final speed(speed at which he hits the ground, not terminal velocity) of 24x9.81 which is roughly 235 m/s, or 846 km/h.Given that when he jumped off he had some vertical velocity, you can add around 3 km/h to the result
The terminal velocity would be about 113.5m/s or 408.6km/h.
Here are my really rough calculations. I don't know the drag coefficient (C) of the T-80U so I just used the coefficient of a rectangular box.
v=â2mg/ÏAC
m=46tons or 41730.5kg
g=9.81m/s^2
Ï=1.2kg/m^3
A=25.2m^2
C=2.1
v=â((2)(41730.5kg)(9.81m/s^2))/((1.2kg/m^3)(25.2m^2)(2.1))
v=113.5m/s or 408.6km/h
If anyone has anything to add or correct just let me know! Love your content Phly, keep up the great work!
Using V=sqrt(2mg/pAC), mass of t80u is 46tonnes or 46000kg, g=9.81, p(density of air) = 1.2, A=surface area: minimum=6.5 maximum=15.8 and finally C(the drag coefficient)= approx. 0.8... Using the different values for areas we get:
minimum terminal velocity of: mach 0.32
maximum of 0.495
@Phly: to your question Projectiles in WT have some kind of limit and they despawn. It's either the ceiling or a distance/lifetime. You can try backing up a howitzer into a trench so you angle your tank to aim vertically and see if the shell actually hits the ground anywhere near you. I couldn't do it with M8 HMC nor with 105mm M4A3
The entire world: 10 Kilometres
Americans: 109.36133 Football fields.
americans: [measuring everything in daily life objects]
europeans: [confused noises]
So how far is Mars away?
Ah, yes, exactly 6942088 snickers
A projectile weight of 4.85kg, a drag coefficient of around 0.5 - 0.4 (taking the attack surface as a cone) and a cross-sectional area of about 12.2 cm^2 (From the stats I've found + the ones in-game, the projectile has a length of 45.2 cm and a diameter of 12.5cm) the round should have a terminal velocity of about 100 m/s - 110 m/s.
(Keep in mind that it's 3am here and I have a splitting headache. Any corrections are more than welcome)
TC: Gunner Sabot tank! Range, seventeen hundred bananas.....
Gunner: um? you ok LT??
So....... if we use the constant for Gravity (9.81 m/s/s), t ~ 23s, and say there is no air resistance for the tank, then we apply some kinematic equations ( v = v0 + at , x = ( {v0+v/2} { t } ) we get a constant velocity of 225.4 m/s. Put this into the second equation and you get 2592.1 m. Apply this to Pythagoras theorem where we use a = 10 km (10000 m) and b = 2592.1 m and solve for c, we get a total of 10330.5 m for the total ground distance of the projectile. Glad i could use the physics that was taught to me for this, because it will probably never be used again. Thanks Public School system!
Thanks for the existential crisis Phly, really appreciate it
*epic 10 kilometer kill*
Me an WT player:
Almost every high rank match in a nutshell
The T-80Uâs terminal velocity would reach up to about 1400 m/s. Given its weight (53500kg), the air resistance per kg, and the height it fell from, it takes about ~30 seconds for it to fall 4000m. The tankâs maximum velocity will be at about ~280m/s, and its terminal velocity would go up to the whopping 1400m/s. I might be very wrong though.
Nonetheless donât drop tanks from the sky please. We donât need another Hiroshima, we have too much anime already.
USSR: "Puny American SR-71 Blackbird, only mach 3.2.
We drop tenk from space, tenk go mach 4.1, tenk shoot plane, plane no more problem. Brezhnev heppi.
this is why this game is so impressive, every single round is calculated from the point it fired to an impact point. that doesnt sound as impressive in a tank but think about all the aircraft firing thousands of rounds a second, ships and tanks all having every round ballistically calculated.
