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 7.42 g and a speed of 291 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.

Mass of the bullet is m=7.42⋅10−3 kg  speed is v = 291 m/s  A soldier on a firing range fires an8-shot burst from an assault weapon at a full automatic rate of 1000 rounds per minute.  Then the average recoil force exerted on the weapon during that burst is calculated as  Favg=(7.42×10−3 kg)(291 ms)  =1000  bullets60 s
