A gun fires bullets of each of ,mass 1gram with velocity of 10m/s by exerting a constant force of 5 g weight. then the number of bullets fired per second is- (g=10 m/s^2)

please me of this problem and let me know the answer in detail.

1gram(v-u)=10number of bullets. We assume bullet is first at rest and then it attains momentum. So 50 = 10*number of bullets/1 second. Thus we get 5 bullets per secondLog in to reply
