The kick experienced when firing a rifle can be explained by Newton’s third law. A .22-caliber rifle has a mass M = 5.2 kg, and a bullet with a mass m = 3.0 g leaves the barrel of the gun at a velocity of 320 m/s. 

(a) If the bullet starts from rest and leaves the gun barrel after t - 0.010 s, what was the acceleration of the bullet? Assume the bullet’s acceleration is constant while it travels along the barrel. 

(b) What was the force on the bullet? 

(c) What was the magnitude of the force exerted on the gun? 

(d) What acceleration did the gun experience? 

(e) Compare the ratio of M and m to the ratio of the accelerations of each object.
