During a lunar mission, it is necessary to increase the speed of a spacecraft by 3.18 m/s when it is moving at 460 m/s relative to the Moon. The speed of the exhaust products from the rocket engine is 1200 m/s relative to the spacecraft. What fraction of the initial mass of the spacecraft must be burned and ejected to accomplish the speed increase?
