- Physics Ninja looks at a problem of a skier sliding down a slope. Conservation of mechanical energy is used to find the maximum height after taking a jump. We also consider the problem when there is friction slowing him down before the jump.
Beautiful problem. It's so nice when everything fits together so nicely!
So clear and well-explained. Appreciate these videos so much; thank you!
I did not study for my exams but watched this before and this video helped me so much. thank you
Glad it helped!
when we found v at the height 2.0m, how do we know the direction of v? how would we have known that the v is in line with the angle of the ramp? in future questions, what determines whether the v is a v_x or v_y or v of some ramp it's being launched? If the surface was flat, would v be in the x direction i presume?
Thank sir it helps a lot
Thank you so much!
You're welcome!
now how in the heck do you do this problem in 3 mins on the exam for ap physics 1
how come when we're looking for Hmax we're using cosine? I would have thought to use sine and Vy instead
😢I'm also thinking that
yeah that sucks, yeah not explain all the things clearly , he just gave us the results ... not explatin them at all
@@SatyajitMahapatra-ss3kpbecause at Hmax the y component of velocity is =0 , while the x component of V is always constant (that's an important characteristic of the projectile motion)
For which standard do you guys, in your country or state study theese kind of problem age guess?

I will try to solve this tomorrow and then I will watch It.
Sir, Why is the value of gravity is not equal to negative -9.8m/s^2?
If that were the case you would GAIN gravitational energy when you move down rather then lose gravitational energy which gets converted to kinetic energy
