Determine the work done by the gas on the bullet

Reference no: EM13341430

A 75-g bullet is fired from a rifle having a barrel 0.558 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 14100 + 9700x - 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 1.11 m long, how much work is done? kJ (c) How does this value compare with the work calculated in part (a)?
