A space shuttle ejects two communication satellites while describing a circular orbit, 296 km above the surface of the earth. Knowing that one of these satellites had a mass of 3600 kg, determine

(a) The additional energy required to place the satellite in a geosynchronous orbit (see Prob. 12.81) at an altitude of 35 780 km above the surface of the earth,

(b) The energy required to place it in the same orbit by launching it from the surface of the earth.
