An air gun fires a bullet by means of compressed air. Simplistically, an air gun can be viewed as a metal cylindrical tube open on one end and plugged air-tight in the middle by the bullet, which is held in place by a trigger. The space between the bullet and the blind end is filled with compressed air. When the trigger is released, the compressed air undergoes a sudden expansion against ambient pressure, pushing the bullet out of the tube...

A 0.026-kg bullet is accelerated from rest to a speed of 565 m/s in a 3.2-kg rifle. The pain of the rifle’s kick is much worse if you hold the gun loosely a few centimeters from your shoulder rather than holding it tightly against your shoulder. For this problem, use a coordinate system in which the bullet is moving in the positive direction. a. Calculate the recoil velocity of the rifle if it is held loosely away from the shoulder....
