change PE= min work
min work= GMm/r1-GMm/R2
M mass of moon, m is mass of lunar
I'm having trouble setting up/solving this physics problem? Can someone please help me? Thank you.
A 4700 kg lunar lander is in orbit 45 km above the surface of the moon. It needs to move out to a 340-km-high orbit in order to link up with the mother ship that will take the astronauts home. How much work must the thrusters do?
