Question: One of your summer lunar space camp activities is to launch a 1190-kg rocket from the surface of the Moon. You are a serious space camper and you launch a serious rocket: it reaches an altitude of 231 km. The mass and radius of the Moon are 7.36 × 1022 kg and 1740 km, respectively.
Part A: What gain in gravitational potential energy does the launch accomplish?
In joules
