Homework Help: An electron is released from rest in a uniform electric field

  1. Jan 27, 2006 #1
    I need help with this question if anyone can give me an idea of what to do. Any help would be greatly appreciated.

    An electron is released from rest in a uniform electric field. The electron accelerates vertically upward, traveling 4.50 m in the first 3.00 micro seconds after it is released.
    What is the magnitude of the electric field?
