    physics homework question

    please dont give me the answer, just give me a clue on how to get started
    the problem is as follows:
    When a traffic light turns green, a waiting car starts off with a constant acceleration of +6.0m/s. At the instant the car begins to accelerate, a truck with a constant velocity of +21 m/s passes in the next lane. How far will the car travel before it overtakes the truck?

    set up as two kinematics equations, set them equal to each other, and solve...

    Hope that wasn't too much.
