A 125-g bullet is fired from a rifle having a barrel 0.580 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 16,000 + 10,000x − 26,000x2, 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. (Enter your answer to at least two decimal...

A bullet with a mass of m = 14.5 g is shot out of a rifle that has length L = 0.98 m. The bullet spends t = 0.16 s in the barrel. Calculate the magnitude of the bullet's acceleration, in meters per second squared, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion. What is the numerical value of the net force FNET in newtons acting on the bullet?
