A 1500 kg satellite is orbiting Earth at a height of 7200 km from the surface.

What is the moment of inertia of the satellite about the center of the Earth? You may treat the satellite as a point mass.

What is the velocity of the satellite? A 500 kg satellite heading the opposite direction with the same speed crashes into the first one in a perfectly inelastic collision.

What is the speed of the wreckage after impact?
