A spacecraft of 140 kg mass is in a circular orbit about the Earth at a height h = 3RE.
(a) What is the period of the spacecraft's orbit about the Earth?
T = h
(b) What is the spacecraft's kinetic energy?
K = J
(c) Express the angular momentum L of the spacecraft about the center of the Earth in terms of its kinetic energyK. (Use the following as necessary: RE for the radius of the Earth, K for the kinetic energy of the satellite, and mfor the mass of the satellite.)
L =
(d) Find the numerical value of the angular momentum.
L = J · s
