A satellite moves in a circular orbit around the Earth at a speed of 5.3 km/s. Find the satellites altitude above the surface of the Earth. Suppose the Earth is a homogeneous sphere of radius Rearth = 6370 kilometer and mass Mearth = 5.98 x 1024 kilogram. You will need G = 6.67259 x 1011 N m2/kg2.
Answer in units of km.
