A ball of mass m collides with a wall with speed v and rebounds on the same line with the same speed. If mass of the wall is taken as infinite, then the work done by the ball on the wall is

A

`mv^2`

B

`1/2 mv^2`

C

`2mv`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:

D

Since the wall has infinite mass therefore the displacement is zero.
