In a futuristic scenario, you are assigned the mission of making inoperative an enemy satellite that is in a circular orbit around earth. 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 9.63 times 102 kg and 2.11 times 102 km. earth's mass and radius are 5.98 times 1024 kg and 6.37 times 103 km.
