Homework Help: Finding Speed

  1. Sep 13, 2007 #1
    1. The problem statement, all variables and given/known data


    A car is moving with constant acceleration covers the distance 74.0m. between two points in time 8.00s. Its speed as it passes the second point is 15.3m/s.

    2. Relevant equations

    The equation I am trying to use, is

    x-x_0 = (v_ox + v_x / 2)t

    3. The attempt at a solution

    I would think that is the correct formula, as we know final displacement of 75m. Initial would be 0m.
    Initial Velocity would be unknown, we are trying to find it.

    Final velocity would be 15.3m/s.
    and time would be 8s.

    I plug does in the equation and solve and I get 3.45 m/s. Am I missing something? wrong equation?..:confused:

    please and thank you

    NVM, my mistake was in calculations. How do I delete this thread. lol
