Help electric fields

  1. Feb 7, 2005 #1
    im not sure how to do this...

    An electron, starting from rest, is accelerated by a uniform electric field of 8.8×104 N/C that extends over a distance of 7.0 cm. Find the speed of the electron after it leaves the region of uniform electric field.

    There are two ways of approaching this problem, one is conservation of energy, the other is motion with constant acceleration (kinematics).. Is there any you prefer or are required to do?

    Do you see why this is constant acceleration?
