$\huge{ \mathfrak{here \: is \: answer}}$


$\bf{see \: in \: pic}$


we have consider two frames of reference s and s', s' is moving with constant velocity (v) along x axis let M1 be the mass of particle moving with velocity u1 in the system s along x axis the corresponding mass and velocity of same particle in s' and m'1 and u'1 respectively...

Answer 2

Heya!!

--------------------------------

Concepts :

1. Velocity addition theorem
2. Law of conservation of momentum
3. Lorentz transformation

Suppose m1 nd m2 collide with each other with u nd - u in S'.

Then we have to find v.

Hope it helps uh!
