A ball of mass m moves with speed v and ...

A ball of mass `m` moves with speed `v` and stricks a wall having infinite mass and it returns with same speed then the work done by the ball on the wall is

A

Zero

B

mv J

C

m/v.J

D

v/m J

Text Solution

Verified by Experts

The correct Answer is:
A
The ball rebounds with the same speed. So change in it.s Kinetic energy will be zero i.e. work done by the ball on the wall is zero
