A 100 g bullet is fired from a rifle having a barrel 0.600 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 15000 + 10000x - 25000x^2, 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 1.00 m long, how much work is done?
(c) How does this value compare with the work calculated in part a? (percent difference)
