Question:

A spaceship is orbiting around the Earth. The mass of Earth is 5.98 x 1024 kg, and the mass of the spaceship is 8600 kg. Let R be the distance from the center of Earth. If this distance changes from position R1 = 7300 km to position R2 = 6700 km, by how much does the kinetic energy of the spaceship increase?
