. A marksman holds a rifle of mass mR = 3.50 kg loosely, so it can recoil freely. He fires a bullet of mass mB = 10 g horizontally with a velocity relative to the ground of vBx = 300 m/s. What is the recoil velocity vRx of the rifle? Find kinetic energy of the bullet and rifle right after firing and tell me which gets more kinetic energy
