Particle's Movement in a Uniform Electric Field

[Krysrhap]

Homework Statement

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 ?

Homework 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![/B]

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![/B]

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