mv1_+mv2 = mv'1+mv'2.
m is equal.
v1+0 = 2v' because v1 = 0 and v'1 = v'2.
v' = v/2.
m is equal.
v1+0 = 2v' because v1 = 0 and v'1 = v'2.
v' = v/2.

Initial velocity = v.
Given condition that both balls are moving.
Hence v/2.
Given condition that both balls are moving.
Hence v/2.

Law of conservation of momentum.
When one ball hits second then the first ill stop & its momentum is transfer to other with the half of the velocity of first ball.
That's why answer = V/2.

After striking the velocity of the two bodies will be reduces why because assume both the two bodies are rotate in CW direction when second body front side touches the first body back side due to same direction speed will be reduces.

Its wrong, only V2 has velocity of V after impact.

It should be perfectly inelastic material then only V/2 answer will be correct.
