This problem involves the energy of circular orbits. We are required to determine the difference in energy between two circular orbits.
The energy of a circular orbit:
A 6000kg lunar lander is in orbit 20km above the surface of the moon. It needs to move out to a 100km -high orbit in order to link up with the mother ship that will take the astronauts home.
How much work must the thrusters do?
