Solving a problem in physics section 30 point 4 mechan

4. Determine the height h, which can be lifted from the Moon rocket mass m = 2 m, if this work is done A = 1 GJ. What kind of energy must be expended T to launch a missile but a circular orbit with a given height? The mass of the moon M = 7,33 ∙ 1022 kg, the radius of the moon R = 1,74 ∙ 106 m.
