Expert Answer:
-While a man fires with a gun, an impulsive force acts on him.
-Impulsive force is the force of impact which two or more bodies exert on one another acts only for a short time, giving a brief but strong push.
-Impulsive Force (I)= m x v = 0.1 kg x 100 = 10 N-s
-The number of bullets fired per second is the ratio of the force required to hold the gun in its position to the impulsive force.
