Two Earth satellites, A and B, each of mass mmm = 930kgkg , are launched into circular orbits around the Earth's center.Satellite A orbits at an altitude of 4000 kmkm , and satellite Borbits at an altitude of 12600 kmkm
What are the potential energies of the two satellites? (inJules)
What are the kinetic energies of the twosatellites?    (in Jules)
How much work would it require to change the orbit of satellite Ato match that of satellite B? (in jules)
hint this is tricky problem
