## Homework Statement

An electron is fired from x = 0 with an unknown V0 at 45 degs to the horizontal between two parallel plates separated by 2 cm. Electric field is 103 j N/C. Find:

a) The max value of V0 so that the electrons don’t hit the upper plate

3.75 * 106 m/s

## Homework Equations

If you find acceleration, it is essentially a kinetics problem

Eq = ma

## The Attempt at a Solution

a = -1.76 * 10^14 j m/s^2

0.02 = v0t -8.8 * 10^13 t^2

Then I have no idea how to solve for either t or V0,

For anybody who has the book university physics, it's number 33
