The expanding gases that leave the muzzle of a rifle also contribute to the recoil. A .30 caliber bullet has mass 7.20*10^-3 and a speed of 601 relative to the muzzle when fired from a rifle that has mass 3.10kg . The loosely held rifle recoils at a speed of 2.05 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.
a) 6.36 kg-m/s
c) 4.33 kg-m/s
d) 11.0 kg-m/s
e) 2.03 kg-m/s
