Q. A satellite with a mass of 750 kg is in orbit around the earth. It is initially located at an altitude (measured from the earth's surface) of 2.12 x 106 m. It is then moved into a new orbit, with an altitude of 4.25 x 10^6 m (again, measured from the earth's surface).
(a) What is the speed of the satellite in its original orbit?
(b) What is the speed of the satellite in its new orbit?
(c) How much work must be done to move the satellite from its original orbit to the new orbit?
