A ball is released from certain height. ...

A ball is released from certain height. It loses 50% of its kinetic energy on striking the ground. It will attain a height again equal to

A

One fourth the initial height

B

Half the initial height

C

Three fourth initial height

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

Because 50% loss in kinetic energy will affect its potential energy and due to this ball will attain only half of the initial height.
