## Homework Equations

x= x.initial + v.initial(t) + .5(a)t^2

v= v.initial + at

v^2= v.initial^2 + 2ad

## The Attempt at a Solution

I tried plugging into above formulas but there were too many unknowns.

I'm not sure what I'm missing. Please help, I'm sure this is a simple question.

Also, only kinematics allowed, not potential energy.
