Hey there,
Impulse per bullet = 1000*0.025 kg-m/s
Unit of impulse is also N-s
Impulse per second = 4*1000*0.025 = 100 N-s
F = 100 N
Hope this helps!

The momentum change in one second =Bullet mass * velocity * rate/second =0.035 * 400 * 400/60 = 93.333 kgm/sSo the rate is 93.333kg.m/s21 Newton is 1 kgm/s/sSo the force is 93N, or the weight of 9.3kg.
