Physics

A satellite in a circular orbit around the earth with a radius1.011 times the mean radius of the earth is hit by an incomingmeteorite. A large fragment (m = 81.0 kg) is ejected in thebackwards direction so that it is stationary with respect to theearth and falls directly to the ground. Its speed just before ithits the ground is 361.0 m/s. Find the total work done by gravityon the satellite fragment. RE 6.37·103 km; Mass of the earth= ME5.98·1024 kg.
