(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An electron with an initial speed of 4.70×10^{5}m/s is brought to rest by an electric field.

What was the potential difference that stopped the electron?

Unknown:

potential difference or [tex]\Delta[/tex]V

Known:

v_{o}=initial speed

m=mass of electron

q=charge of electron

2. Relevant equations

[tex]\Delta[/tex]Vq+[tex]\frac{1}{2}[/tex]*mv^{2}=[tex]\Delta[/tex]Vq

3. The attempt at a solution

I figure basically plug and chug but my equation doesn't seem right. I sure it's not. Basically I don't know where to go from here.
