An artificial satellite is traveling 8.0 x 10 m/s in a circular orbit. Assuming g= 9.7 m/s at that altitude, what is
the orbital radius of the satellite?
What velocity would a satellite need to maintain a circular orbit at a height h = RE (RE = 6.37 x 103 km) above the surface of the Earth (ME = 5.97 x 1024 kg)?
A geosynchronous orbit for a satellite is a circular orbit about the equator of the Earth in which the satellite stays fixed over a point on the equator. Use the fact that the Earth makes one revolution about its axis every 24 hours to find the altitude in miles of a communications satellite in geosynchronous orbit. Assume the Earth to be a sphere of radius 4000 mi.
