1. The problem statement, all variables and given/known data A rifle weighs 50.0 N, and its barrel is 0.750 m long. It shoots a 25.0 g bullet, which leaves the barrel at a speed (muzzle velocity) of 320 m/s after being uniformly accelerated. What is the magnitude of the force exerted on the rifle by the bullet? 2. Relevant equations F=MA w=mg v=v0+at v2=v02+2ax 3. The attempt at a solution I wasn't totally sure of what I was doing, but this is what I did: I used the equation: v2=v02+2ax and did-- 3202=0+2(a)(.750) and I got 68266.67 m/s2. I dont know if I did this right, or if I even used the right equation. Then I used the F=MA equation. F=.25(68266.67) to get 17067 N, but when I typed in that answer to Webassign, it was wrong. Any help would be greatly apprecitated. Thank you!
