I have no idea...I suck at physics

If anyone can solve this or at least point me in the right direction I'll give you 1 million internets.

Two charged, parallel, flat conducting surfaces are spaced d=1.00cm apart and produce a potential difference (delta)V = 625V between them.  An electron is projected from one surface directly toward the second.  What is the initial speed of the electron if it stops just at the second surface?

W = qV
W = .5mv^2

qV = .5mv^2
2qV/m = v^2
v = sqrt(2qV/m)
