The International Space Station ( or ISS) has an orbit around the Earth at an altitude of about 400 km above the Earth’s surface, which is low enough that the F=mg version of gravity still works. The ISS goes around the Earth roughly every 90 minutes. The mass of the ISS is about 450,000 kg. The radius of the Earth is about 6,370 km. Does the ISS have more kinetic or potential energy?

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 975 kg and 259 km. Earth's mass and radius are 5.98×1024 kg and 6370 km.W = ? J
