A 998-kg satellite orbits the Earth at a constant altitude of 98-km.(a) How much energy must be added to the system to move the satellite into a circular orbit with altitude 210 km?(b) What is the change in the system's kinetic energy?(c) What is the change in the system's 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 969 kg and 299 km. Earth's mass and radius are 5.98×1024 kg and 6370 km.
