A rock is dropped from a distance above the surface of the earth and is observed to have kinetic energy
when it hits the ground.
For another rock, It is dropped from twice the height above the earth’s surface and has kinetic energy
when it hits.
For the first rock, ..............(1)
For the second rock, ..............(2)
Dividing equation (2) by (1) we get :
Hence, this is the required solution.
