This topic appreciated in 7 different Physics Olympiads including INPhO
The first variant is of RMPh
as far as I observed I'll share each variant daily
By the way this is from SWISS PHYSICS OLYMPIAD
Meaning Wo means you have to find in terms of l
Also what I can feel is that you have to choose axis carefully this is the game all about
If we choose wrong axis (means the standard one) it will get us into lengthy method ((
So everyone MUST TRY :)
Please try B part first
A wonderful of CPhO
Note that it is translated and meaning of impulse and momentum in Chinese are same
So just identify through symbol like here P so consider it as momentum
Just tell me how many solution of this problem are possible??
Beautiful idea :)
