Homework Help: Help with electric field acceleration problem.

  1. Jan 24, 2008 #1
    1. The problem statement, all variables and given/known data

    An electron is accelerated by a constant electric field of magnitude 300 nC. a) Find the acceleration of the electron. b) Use the equations of motion with constant acceleration to find the electron's speed after 1.00x10^-8 seconds.

    3. The attempt at a solution

    I'm not sure where to start with finding the acceleration, but once I know how to do that part b is easy. Do I just plug in the elementary electron charge along with F=qE then use F=MA to solve?
