Question 1064148: Tanner(at rest) fires a 4.00-kg gun that expels a bullet of mass .0140kg with a velocity of 181 m/s. Tanners mass is 60.0-kg, and holds the gun tightly against his shoulder so the recoil moves both the gun and him backwards together. What is his velocity after firing the gun?

Apply the "Momentum conservation Law":

0.014*181 = (60+4)*v,

where v is the velocity under the question.

Find v from this equation.
