Chapter 8, Problem 8.17E
The expanding gases that leave the muzzle of a rifle also contribute to the recoil. A .30-calibcr bullet has mass 0.00720 kg and a speed of 601 m/s relative to the muzzle when fired from a rifle that has mass 2.80 kg. The loosely held rifle recoils at a speed of 1.85 m/s relative to the earth. Find the momentum of the propellant gases in a coordinate system attached to the earth as they leave the muzzle of the rifle.
