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 295 m/s relative to the ground as it leaves the barrel of the weapon.
a). Calculate the average recoil force (in N) exerted on the weapon during that burst.
The firing time for each shot is
t = 1 minute / 1000 shots = 60/1000 = 0.06 seconds.
according to ...
It shows how to calculate the average recoil force exerted on the weapon during that burst.
