A machine gun is mounted on a flat rail car. The gun is firing bullets at the rate of 10 bullets per second each of mass 10 g. The bullets come out with velocity 500 ms^(-1)from the rear. Calculate the acceleration of the car at the instant when its mas is 200 kg. Also calculate the force at that instant.
