1. The problem statement, all variables and given/known data A satellite moves in a circular orbit around Earth at a speed of 4505 m/s. a) Determine satellite's altitude above surface of the Earth. b) Determine the period of satellite's orbit. 2. Relevant equations I'm not sure about equations for the altitude, but I know the period has something to do with Kelper's laws & T^2=(4pie^2/GMe)r^3=KeR^3 3. The attempt at a solution My attempt was to use the above equation with G=6.67x10^-11 & Me=6378.1 It wasn't right.
