Physics Meteorite

posted by .

A satellite in a circular orbit around earth with a radius 1.019 times the mean radius of the earth is hit by an incoming meteorite. A large fragment m=60 kg is ejected in the backwards direction so that it is stationary with respect to the earth and falls directly to the ground. Its speed just before it hits the ground is 373 m/s.
A. Find the total work done by gravity on the satellite fragment.

B. Find the amount of that work converted to heat
