Question

In principle, when you fire a rifle, the recoil should push you backward. How big a push will it give? Let's find out by doing a calculation in a very artificial situation. Suppose a man standing on frictionless ice fires a rifle horizontally. The mass of the man together with the rifle is 70 kg, and the mass of the bullet is 10 g. If the bullet leaves the muzzle at a speed of 500 m/s, what is the final speed of the man?

Part A
In principle, when you fire a rifle, the recoil should push you backward. How big a push will it give?
Let's find out by doing a calculation in a very artificial situation. Suppose a man standing on frictionless
ice fires a rifle horizontally. The mass of the man together with the rifle is 70 kg, and the mass of the
bullet is 10 g.
If the bullet leaves the muzzle at a speed of 500 m/s, what is the final speed of the man?
