Example #1 A marksman holds a rifle of mass m Rx = 3.00 kg loosely in his hands, so as to let it recoil freely when fired. He fires a bullet of mass m B = 5.00 g horizontally with a elocity relative to the ground of v x = 300 m/s. What is the (vector) momentum of the velocity relative to the ground of v Bx 300 m/s. What is the (vector) momentum of the system (rifle + bullet) before and after the man fires the bullet?
