Particle's Movement in a Uniform Electric Field

  1. Sep 5, 2015 #1
    1. The problem statement, all variables and given/known data
    A particle with a mass of 1.5×10−5kg and a charge of +2.9 μC is released in a (parallel plate) uniform horizontal electric field of 11 N/C .

    How far horizontally does the particle travel in 0.40 s ?

    2. Relevant equations
    I think some of the kinematic equations are needed, but it's been so long since I took that part of physics, I'm not sure which one to use!

    3. The attempt at a solution
    I don't even know where to start. I think I have to find the particle's acceleration first, but I'm not even sure how to do that!

    Getting the acceleration sounds like a good idea. How about using Newton's second law?
