A110-g bullet is fired from a rifle having a barrel 0.636 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 13500 + 11000x - 25750x2, 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 1.02 m long, how much work is done?


(c) how does this value compare with the work calculated in part (a)?
