- Physics Ninja looks at the Ballistic Pendulum physics problem. A bullet is fired into a heavier wooden block and the system swing up some height H. Conservation of linear of momentum is used followed by conservation of energy during the swing portion. A numerical example is done at the end to find the initial velocity of the bullet
Amazing. An excellent video I truly appreciate THIS content
Thank you so much. Just one question. Why is the string tension force always perpendicular to the block's movement? As in the diagram it is making a theta angle.
Let me take it further. what is the minimum required speed of the bullet in order to turn the pendulum a full circle without loosen the rope tension
Great video, thanks!
thank you sir, love from india
Thank you so much
so clear explanation thank you
Hi, just wondering how you find the maximum angle moved from the vertical by the block of wood. any tips are greatly appreciated!
If you know the maximum height and the length of the string try drawing a triangle and use trigonometry to find the maximum angle.
@@PhysicsNinja what if you're not given the length of the rope in the question? I'm doing one which has most of the variables apart from the length
what if you're given the length of the string and the maximum angle, how do you find h?
H=L-Lcos(theta). If theta=0, H=0, if theta=90, H=L.
@@PhysicsNinja thank you so much!
Where did you get this problem? This problem was in my midterm exam and i expect that my professor writes final exam questions in similar book , but i can’t find the original textbook. Can you help me:)?
This problem is found in a lot of college level Physics books.
I know but my midterm problem has exact same situations, figures you solved in your video! I want the exact textbook name. If you don't know, it will be okay:) I'm sorry that I'm not good at English. Thank you!
If we have a pendulum assembly with a rod (mass is 20 g) do we include that for the uppercase M or do we just look at the mass of the block rather than the mass of the whole pendulum assembly? Also, how would we measure the angle it reaches with a protractor? Would it be from the right edge of the block or from the top of the pendulum assembly because I am getting two different values? Thanks :)
Lmao imagine if he responds after a year
@@armanbarzani4148 I don't think that's happening at this point lol plus I finished my physics sequence last semester
Thanks sir, what if the quastion gave the tention in the cord after the swing. how would we write the energy then
Hi, I need help with this question but it's a little different. Can you please help me?
How would you solve for height if it is not given? (vertical displacement and length of string is given)
What if you don't have the maximum height only the speed right after the collision?
Awesome video, thanks I understand! Would this be considered a perfectly inelastic collision, or simply an inelastic collision?
He states the answer to your question right there in the video
why nobodies solving for maximum angle after collision xD
