AP Equation for delta t

In addition to your assignment, I am asking you to develop an expression for delta t if given vi, a, and delta x, starting from the two equations

delta x =( vf^2-vi^2)/2a and delta t = (vf-vi)/a.

Its ugly, but easier than using the quadratic equation to find delta t from
delta x = vi delta t + a/2 delta t^2.

Good luck and don't work too hard on it. Bring in what you've done and we'll go over it in class.
