An orbiting satellite has a mass of 5000 kg and is traveling at a constant velocity of V0. To alter its orbit, an attached rocket discharges 100 kg of gases from the reaction of solid fuel at a speed of 3000 m/s relative to the satellite in a direction opposite to V0. The fuel discharge rate is constant for 2 seconds. Determine (a) the thrust exerted on the satellite, (b) the acceleration of the satellite during this 2-second period, and (c) the change of velocity of the satellite during this time period
