Question

A satellite is moving with a constant speed v in circular orbit around the earth. An object of mass ' m ' is ejected from the satellite such that it just escapes from the gravitational pull of the earth. At the time of ejection, the kinetic energy of the object is:, 3 2 m v 2, m v 2, 1 2 m v 2, 2 m v 2
