A 136 g bullet is fired from a rifle having a barrel 0.935 m long. Assuming the origin is placed where the bullet begins to move, the force exerted on the bullet by the expanding gas is F = a + bx - cx^2, where a = 20600 N, b = 5680 N/m, c = 39900 N/m^2, with x in meters.

Determine the work done by the gas on the bullet as the bullet travels the length of the barrel.
