The kinetic energy of a body of mass 5 kg is 100 J. When it is thrown up then the height to which it goes up, is`(g=10m//s^(2))`

A

5m

B

1m

C

2m

D

10m

Verified by Experts

The correct Answer is:

C

Whe the ball falls from a height h, the decrease in potential energy=mgh=`20xx9.8xx0.5=98J`.
