A body of mass 1 kg falls to the ground ...

A body of mass 1 kg falls to the ground from the roof of a building 20 m high. Find its
(iv) kinetic and potential energies at a position 2 m above the earth's surface.

Text Solution

Verified by Experts

Potential energy at a height of 2m
`=1xx9.8xx2 =19.6 J`
`therefore` Kinetic energy at that height of 2m = decrease in initial potential energy =196 -19 .6 = 176 .4 J.
