A machine gun is mounted on a flat rail road car. The gun is firing bullets at the rate of 20 bullets per second each of mass 10 g. The bullets come out with velocity 500 ms^(-1). Calculate the acceleration of the car at the instant when its mass is 200 kg. Also calculate the force at that instant.
