A satellite is orbiting around the earth in a circular orbit. Its orbital speed is V_(0). A rocket on thrust to the satellite directed radially away from the centre of the earth. The uration of the engine burn is negligible so that it can be considered instantaneous. Due to this thrust a velocity variation DeltaV is imparted to the satellite. Find the minimum value of the ratio (DeltaV)/(V_(0) for which the satellite will escape out of the gravitational field of the earth.
