1. The problem statement, all variables and given/known data A 10g bullet accelerates from rest to 500m/s in a gun barrel of length 10cm. Find the accelerating force (assuming it is constant). 2. Relevant equations F=ma, v^2=vo^2+2a(x-xo)? 3. The attempt at a solution I tried using F=ma, but it does not equal the answer in the back of the book.
