Question: A satellite moves in a circular orbit around the Earth at a speed of 5.5 km/s. Assume the Earth is a homogeneous sphere of radius 6370 km and mass 5.98 x 1024 kg. The value of the universal gravitational constant is 6.67259 x 10-11 N*m2/kg2.
Part A: Determine the satellite's altitude above the surface of the Earth.
I need help to find the satellite's altitude above the surface of the Earth.
