Current Attempt in Progress

An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate $($see the drawing$).$ The plates are separated by a distance of $1\mathrm{.}5cm,$ and the electric field within the capacitor has a magnitude of $2\mathrm{.}5{10}^6\frac{V}{m}.$ What is the kinetic energy of the electroj just as it reaches the positive plate?
