Communications satellites are placed in a circular orbit where they stay directly over a fixed point on the equator as the earth rotates. These are called geosynchronous orbits. The radius of the earth is , and the altitude of a geosynchronous orbit is ( 22000 miles).
A) What is the speed of a satellite in a geosynchronous orbit?
B) What is the magnitude of the acceleration of a satellite in a geosynchronous orbit?
