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?
