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 6.37 x 10^6 m , and the altitude of a geosynchronous orbit is 3.58 x 10^7 m ( approx. 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?
