Q. 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
Explanation
(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
