Imagine I were to shoots a .30 caliber rifle at a 0.56 kg block of wood. The rifle and wood are mounted on separate carts that sit atop an air track (like a linear air hockey table--ie. frictionless). The 6.4 kg rifle fires a 33 gram bullet at 219 m/s in the positive direction. What would be the velocity of the rifle after the bullet is fired?
