Suppose the moon were held in its orbit not by gravity but by the tension in a massless cable. You are given that the period of the moon's orbit is T = 27.3 days, the mean distance from the earth to the moon is R = 3.85 x 108 m, and the mass of the moon is M = 7.35 x 1022 kg.
1) What is the speed of the moon in its orbit about the earth?
m/s
2) What is the acceleration of the moon in its orbit around Earth?
m/s/s
3) What would the tension in the cable be?
N
