1. The problem statement, all variables and given/known data A satellite that has a mass of 300 kg moves in a circular orbit 5.00 X 107 m above Earth's surface. (a) What is the gravitational force on the satellite? (b) What is the speed of the satellite? (c) What is the period of the satellite? 2. Relevant equations Fg= GMEm/(r+rE T2= [4pi2/G(ME+m)]*(r+rE)3 3. The attempt at a solution Fg= 38N T=37 hours V=9572517 m/h I think the gravitational force might be right but the speed and period seem to be ridiculously too large.
