Hello,

So I was watching this video on youtube

https://www.youtube.com/watch?v=HEfHFsf ... EfHFsfGXjs

I was curious if anyone could provide some insight to the problem above?

Could you just use the conversation of energy principle [work energy theorem] here?

Or is there something that I am missing

P.S: not looking for solutions, I want to figure it out, but if someone could let me know if I am on the right track it would be appreciated

## Pi due to masses of the order of 10 bouncing off each other

The video you linked has fairly detailed explanations. The problem is set up by collisions in classical physics, but it quickly becomes a couple of interesting problems in maths.

For insight into the physics, see the Momentum chapter on Physclips

But that is fairly straightforward.

For the maths, see the video you cite and a link in it.
