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

An electron is accelerated from rest by a potential difference of 422 V. What is its velocity?

2. Relevant equations

KE = .5mv^2

3. The attempt at a solution

Since the electron started from rest, there is no KE at the start, just potential. After it is accelerated I assumed that there was not potential and that the electron only had potential energy.

Doing this, i was able to set up a conservation of energy equation where:

422 = .5mv^2

is this the correct way of going about solving this?
