## Homework Statement

Suppose an object has a velocity [itex]v[/itex] and an acceleration of [itex]a[/itex], where [itex]a[/itex] is negative. The object will eventually reach a velocity of zero [itex]v = 0[/itex]. How much distance will the object travel until [itex]v = 0[/itex]?

## Homework Equations

v = u + at

s = 0.5(u+v)t

s = ut + 0.5 at

^{2}

v

^{2}- u

^{2}= 2as

## The Attempt at a Solution

Since v

^{2}- u

^{2}= 2as, s = -u

^{2}/2a. I implemented this formula into a program I am using, but the object did not stop at the given distance. Am I doing something obviously wrong here? Any help would be greatly appreciated.
