Part A. Suppose you are at the earth's equator and observe a satellite passing directly overhead and moving from west to east in the sky. Exactly 13.0 hours later, you again observe this satellite to be directly overhead. Assume a circular orbit. How far above the earth's surface is the satellite's orbit?
Part B. You observe another satellite directly overhead and traveling east to west. This satellite is again overhead in 13.0 hours. How far is this satellite's orbit above the surface of the earth?
