A body of mass `M` moves with velocity `v` and collides elasticity with another body of mass `m(M gt gt m)` at rest , then the velocity of the body of mass `m` is

A

v

B

2v

C

`v//2`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
B
When target is very light and at rest then after head on elastic collision it moves with double speed of projectile i.e. the velocity of body of mass m will be 2v.
