How do you solve for time if a, v, and s are given

[Newonsite]

Homework Statement

I need to find the time it takes a load to reach the end of a distance. Velocity and acceleration are also given.

Homework Equations

I was thinking of using t=vf-vi/(a) but this does not incorporate distance which I already have.
I would use the above formula to calculate distance (s=vi(t)+0.5(a)(t)^2) but I would need time to solve it and that is what I am solving for.

The Attempt at a Solution

No real attempt as I am not sure if I am using the correct formula.[/B]

I would use the above formula to calculate distance (s=vi(t)+0.5(a)(t)^2) but I would need time to solve it and that is what I am solving for.

Why can't you solve this equation for t?

Are you familiar with the quadratic formula from 1st year Algebra?

Does the statement of the problem say or imply that the acceleration is constant? If it isn't, you cannot use the relevant equation that you quoted.
