Two Earth Satellites, C and D each of mass m=950 kilogram are launched into circular orbit around the Earths center. Satellite C orbits at an altitude of 4200 kilometer, and satellite D orbits at an altitude of12,600 kilometer.
(a) Determine the potential energies of the two satellites?
(b) Determine the kinetic energies of the two satellites?
(C) Determine how much work would it require to change the orbit of satellite C to match that of satellite D?
