  1. Sep 23, 2009 #1
    1. The problem statement, all variables and given/known data

    an electron has an initial speed of 1.43 * 10^5 m/s^2
    if it undergoes an acceleration of 2.3 * 10^14 m/s^2
    how long will it take to reach a speech of 7.47 * 10^5 m/s?
    Answer in units of s.

    and then part B is asking
    how far has it traveled in this time? answer in units of m

    i need to know how to get the answer, step by step please.
