A tennis ball dropped from a height of 2 m rebounds only 1.5 metre after hitting the ground. What fraction of energy is lost in the impact?

A

`(1)/(4)`

B

`(1)/(2)`

C

`(1)/(3)`

D

`(1)/(8)`

Text Solution

Verified by Experts

The correct Answer is:
A
Fractional loss `= (Delta U)/(U) = (mg (h-h.))/(mgh)= (2-1.5)/(2)= (1)/(4)`
