## Homework Statement

A .8kg cannon ball is shot out of a cannon with force 2000-100,000t. When the ball leaves the cannon, the force is zero. What is the velocity of the ball as it leaves the cannon.

Although the problem doesn't specify, I assume there is no gravity or any other external forces since there is no angle of the force or cannon given.

## Homework Equations

F=ma

Unfortunately, I have not learned how to solve equations dealing with varying acceleration, so I don't really know what to do...

## The Attempt at a Solution

I found that the cannon ball leaves the cannon at t=.02, but I don't know what to do once I have that to find the final velocity...
