Essay
A 60.0-kg satellite is in orbit a distance 2000 km above the surface of the earth. The mass of the earth is 5.976 x 1024 kg and the radius of the earth is 6.378 × 106 m.
(a) What is the change in the gravitational potential energy if the satellite moves to a circular orbit 5000 km above the surface of the earth?
(b) What is the change in kinetic energy if the satellite moves to a circular orbit 5000 km above the surface of the earth?
(c) How much work must be done on the satellite to move it to a circular orbit 5000 km above the surface of the earth?
