A 10.0 g bullet leaves a rifle with a speed of 800.0 m/s. (a) What should be the minimum mass of the rifle in order that its recoil speed cannot possibly exceed 2.50 m/s? (b) Make any convenient estimate of the length of the barrel and then calculate the following values for the bullet: time, net force, and net impulse. Compare to the change in momentum. (c) Consider the person firing the rifle – would the impulse of the rifle acting on the person depend on the mass of the rifle? Explain.
