Problem 29P

Problem 29P

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?

Step-by-Step Solution:

Solution 29P

Step 1 of 3

Part a

A geosynchronous satellite takes 24 hours to orbit once around the Earth. This is the same as the Earth takes to complete one rotation about its axis.
