4) a satellite, mass m, is in circular orbit (radius r) around the earth, which has mass me and radius re. the value of r is large enough that you cannot assume the force of gravity is the same as it is at the surface of the earth. (a) what is the kinetic energy of the satellite? your answer should be in terms of g, me, m, and r only. (15) (b) in terms of given quantities, calculate the period of the orbit. how does it depend on m? (10) (c) show that gravity does zero work on the satellite while it is in circular orbit. (d) what is the total mechanical energy, e, of the satellite, and why is the answer negative? your answer should be in terms of g, me, m, and r only. (5)
