A 14.1-g bullet is accelerated from rest to a speed of 793 m/s in a rifle barrel of length 66.9 cm.

(a) Find the kinetic energy of the bullet as it bullet as it leaves the barrel.

(b) Use the work-kinetic energy theorem to find the net work that is done on the bullet.

(c) Use the result to part (b) to find the magnitude of the average net force that acted on the bullet while it was in the barrel.

(d) Now model the bullet as a particle under constant acceleration. Find the constant acceleration of the bullet that starts from rest and gains a speed of 793 m/s over a distance of 66.9 cm. 

(e) Modeling the bullet as a particle under a net force, find the net force that acted on it during its acceleration.
