Questions
N bullets each of mass m kg are fired with a velocity v rn/s, at the rate of n bullets per second, upon a wall. The reaction offered by the wall to the bullets is
detailed solution
Correct option is A
Total mass of N bullets = N mMomentum of N bullets = N m yChange in momentum per second = (N m v) n(where n is the number of bullets fired per second)We know that rate of change of momentum of bullets isequal to the force exerted by the bullets on the wall. Thisis equal to the reaction force offered by the wall to thebullets.Talk to our academic expert!
