Calculating Electron Speed from Accelerating Potential

[redneckpyhsic]

Homework Statement

Derive the equation that would allow you to calculate the speed of the electrons from the accelerating potential.

Homework Equations

Fnet=ma
Ek=1/2mv^2
Ft=mv

The Attempt at a Solution

F=mv/t F=ma
a=v/t ?

I'm not even sure what it means by accelerating potential...

That just means that an electrical source is providing a potential difference to accelerate the electron from rest to velocity 'v' .

Fe=Eq
F=mv/t
q=mv/tE
is that what it means?

Work done by a pd = VQ, charge of an electron is e.
