A soldier on a firing range fires an 8-shot burst from an assault weapon at a full automatic rate of 1000 rounds per minute. Each bullet has a mass of 7.48 g and a speed of 294 m/s relative to the ground as it leaves the barrel of the weapon. Calculate the average recoil force exerted on the weapon during that burst.

The average recoil force exerted on the weapon during that burst is 36.65 N

Explanation:

Bullet Mass - m = 7.48 * kg.

Bullet Speed - v = 294 m/s.

This way knowing that for each firing, the time elapsed is

Δt = 60 s / 1000 rounds = 0.06 s / round.

The average recoil force exerted on the weapon during that burst is given by F = -mv/Δt

F = -mv/Δt = -(7.48 * kg)*(294 m/s) / 0.06s = -36.65 N.

The negative sign means it is directed in an opposite direction of the bullet.
