A sattelite is rotatin in a circular orbit with radius r = 1000 km aroud earth. The mass of the sattelite is m = 1000 kg. The mass of earth is M = 6 x 10^24 kg.

a) What is the velocity of the sattelite?

b) The engine of the sattelite is turned on and it changes its orbit to a new orbit with radius r = 500 km. How much work (W=?) should the engine do for this change of orbit?
