    final velocity
    a car, initially at rest, is accelerated at 10m/s^2 over a distance of 40m.
    what will the final velocity of the car be after is has travled 40m?

    Use the formula



    where Vf = final velocity and Vi = initial velocity, which you know is zero. From this you can calculate Vf.

    Use the formula



    where are respectively final velocity, initial velocity, acceleration and distance traveled.

    Ops, I posted at the same time as ebaines (the screen did not refresh so I could know this only after clicking "Answer" icon, an admin can delete this my post without problems)...
