Consider the elastic collision f two bodies A and B of equal mass. Initially B is at rest and A moves with velocity `v`. After the collision -

A

the body A trace, its path back with the same speed

B

the body A comes to rest and B moves aways in the direction of A' s approach with the velocity u

C

both the bodies stick together and are at rest

D

B moves along with velocity u/2 and A retraces its path with velocity u/2
