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.
sorry for the late reply. the block has the strings going through the top of it, and the sign is hanging down directly from the strings. the bullet impacts the face of the sign, not the side, like the image shows. this, the sign swings radially, with respect to wherever the signs are connected to a tree/pole.
Hi, I have a question. How can you conclude there is conservation of energy if this is an inelastic collision? Wouldn't there be loss of energy after the collision?
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 :)
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:)?
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!
Amazing. An excellent video I truly appreciate THIS content
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

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!
Thanks sir, what if the quastion gave the tention in the cord after the swing. how would we write the energy then

Only conserved after the collision. Not conserved during the collision.
Great video, thanks!
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
thank you sir, love from india
Thank you so much
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?
Hi, I need help with this question but it's a little different. Can you please help me?

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

This problem is found in a lot of college level Physics books.

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
