## Homework Statement

Force and Impulse:

The magnitude of an unbalanced force on a 10 kg object increases at a constant rate from 0N to 50N in 4.0s, causing the initially stationary object to move.

What is the speed of the object at the end of the 4.0s?

## Homework Equations

[not sure] ..

mv = Ft ??

## The Attempt at a Solution

v = Ft / m = (50N)(4.0s) / (10kg) = 20m/s

Thanks for any help = ) very appreciated
