So I have the formula and values substituted in correctly - but now the simple algebra part is killing me.
x = vt + 1/2at^2
.06=(2*10^3)t + 1/2(4*10^7)t^2
What is t?

Reason: Fixed typos.
Yikes! You should have studied Quadratic Equations over the previous years.
If you write it like this: Żat^2 + vt - x = 0, you should find solutions from the Quadratic Equation, or Completing the Square. Ringing any bells, yet?
