Homework Help: Figuring out time when you have acceleration and distance.

  1. Aug 24, 2011 #1
    How long does it take a car to travel 30.0m if it accelerates at a rate of 2.00m/s^2?
    Distance- 30.0m

    Do I need to find vi?

    You must need to assume it is initially at rest, otherwise the problem is incomplete.

    So now I have
    Distance- 30.0m
    So can i now use the d=1/2at^2 formula?
    But we're solving for t
    making the equation t, taking the square root of 2d/a right?
