A 50-g bullet is fired from a rifle having a barrel 0588 m

Question

Solve the all parts of following question given below:

Question: A 50-g bullet is fired from a rifle having a barrel 0.588 m long. Choose the origin to be at the location where the bullet begins to move. Then the force (in Newton's) exerted by the expanding gas on the bullet is 15300 + 10500x - 23750x², where x is in meters.

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

kJ

part B: If the barrel is 0.92 m long, how much work is done?

kJ

part C: How does this value compare with the work calculated in part (a)?

percent difference = %

I need help to determine the work done by the gas on the bullet as the bullet travels the length of the barrel.
