Calculate the speed of a satellite moving in a circular orbit about the Earth at a height of 2700×103 m. The mass of the Earth is 5.98×1024 kg and the mass of the satellite is 1400 kg.

Answer 1

use the masses of the Earth and the satellite to find the gravitational force
... this force equals the centripetal force

(m * v^2) / r = gravitational force

the distance in the gravitational formula is between the centers of the masses
