I was just wondering if any of you could help me figure out this calculus problem, as I am totally stumped and not sure where to start.
"A solider in a firing range fires an 8-shot burst from a weapon at a rate of 1000 rounds per minute. Each bullet has a mas of 7.45g and a speed of 293 m/s relative to the ground as it leaes the barrel of the weapon. Calculate the average recoil force exerted on the weapon during that burst."
I'm not sure if I'm supposed to use integrals here, since force = the derivative of momentum and the integral of F(t)dt = the integral of (dp(t)/dt)*dt.
And I also think that since I can calculate the difference between the initial and final momenta p0 and p1 and since p = mv, then delta p = p0-p1 = mv0-mv1, am I right in this regard?
Thanks a lot for your help!
