1. The problem statement, all variables and given/known data A 95-g bullet is fired from a rifle having a barrel 0.540 m long. Choose the origin to be at the location where the bullet begins to move. Then the force (in newtons) exerted by the expanding gas on the bullet is 16200 + 9400x - 23750x2, where x is in meters. (a) Determine the work done by the gas on the bullet as the bullet travels the length of the barrel. (b) If the barrel is 0.96 m long, how much work is done? (c) How does this value compare with the work calculated in part (a)?(% difference) 2. Relevant equations W = force * displacement 3. The attempt at a solution after plugging in 0.54 in the force equation i got F = 14,350.5 N then multiplied it by 0.54 to get work and got 7.75 kJ same for the second part but i got both answers wrong, i thought it was a simple problem but i guess not.
