1. The problem statement, all variables and given/known data A rocket is launched at a planet of 600km radius, 5.29e22 kg mass, and 9.8068 m/s^2 surface gravity such that it reaches a maximum height 'h' with work 'x'. What is the value of 'x'? Ignore air resistance, and gravity is dependent on height. 2. Relevant equations Unsure of where to start. 3. The attempt at a solution None.
