A 120 kg rocket is moving radially outward from the earth at an altitude of 230 km above the surface with a velocity of 3.7 km/sec. At this point, its final stage engine shuts off. 1- Ignoring any minor air resistance, what is the rocket's velocity 940 km above the surface of the earth?"
2- Again ignoring any minor air resistance, what is the rocket's velocity 940 km above the surface of the earth if its mass were 240 kg?
3- What is the maximum height of the rocket above the earth's surface (using the initial rocket mass of $
