How much work would be required to move the moon (7.36 E 22 kg) from its current obit of 385 E 6 m to an orbit of 504 E 6 m. Assume the mass of the earth to be 6.00 E 24 kg and G = 6.67 E -11. Include the correct sign. This would be work external to the earth/moon system, not gravitational work. Think of it as the energy that would have to be added or removed from the system to allow the calculated change in gravitational potential energy.
