## Homework Statement

A 16 g bullet is accelerated in a rifle barrel

72.3 cm long to a speed of 1010 m/s.

Use the work-energy theorem to find the

average force exerted on the bullet while it is

being accelerated. Answer in units of N.

## Homework Equations

W=changeKE

## The Attempt at a Solution

Fx=(mvf^2)/2-(mvi^2)/2

F=((16*1010^2)/2*.723

F=1.1287e7

Did I do this correctly?
