A spy satellite is in circular orbit around Earth. It makes one revolution in 6.01 hours.
(a) How high above Earth's surface is the satellite?
[Answer in Km]
(b) What is the satellite's acceleration?
[Answer in m/s^2]
I see this posted over and over again and I have about 4 equations, 20 different answers, and none are correct.

NOTE: There is no radius or velocity available to enter into the equations. I have used T=2 pi sqrt(r^3/G) and the r is bigger than earths radius so I can't subtract! are my units jacked up or what! I have spent hours on this and I can't stand it anymore!!!!
