Two Earth satellites, A and B, each of mass m = 960 kg, are launched into circular orbits around the Earth's center. Satellite A orbits at an altitude of 4500 km, and satellite B orbits at an altitude of 13600 km. a) What are the potential energies of the two satellites? b) What are the kinetic energies of the two satellites? c)How much work would it require to change the orbit of satellite A to match that of satellite B?
