Question:
Communications satellites are placed in circular orbits where they stay directly over a fixed point on the equator as the earth rotates. These are called geosynchronous orbits. The altitude of a geosynchronous orbit is 3.58 × 107 m (≈ 22,000 miles).
(a) What is the period of a satellite in a geosynchronous orbit?
(b) Find the value of g at this altitude.
(c) What is the weight of a 2000 kg satellite in a geosynchronous orbit?
