How much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 4500 km above the surface?
Express your answer to three significant figures.
In a futuristic scenario, you are assigned the mission of making an enemy satellite that is in a circular orbit around Earth inoperative. You know you cannot destroy the satellite, as it is well protected against attack, but you can try to knock it out of its orbit so it will fly away and never return. What is the minimum amount of work ?� applied to the satellite that is required to accomplish that? The satellite's mass and altitude are 969 kg and 299 km. Earth's mass and radius are 5.98×1024 kg and 6370 km.
