1. The problem statement, all variables and given/known data 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]? 2. Relevant equations v = u + at s = 0.5(u+v)t s = ut + 0.5 at2 v2 - u2 = 2as 3. The attempt at a solution Since v2 - u2 = 2as, s = -u2/2a. 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.
