1. The problem statement, all variables and given/known data What is the average force applied by a 75 g bullet that leaves a gun at 1350 m/s and hits a target 75m from the barrel of the gun? 2. Relevant equations F = ma 3. The attempt at a solution First I had the equation F = ma, and began filling in all the variables I could. In this case, I only started with the mass. As for acceleration, I don't know how to find it. Could I rearrange Vf^2 = Vi^2 + 2ax to solve for a? If so, what's the final and initial velocity?
