Stopping distance

  1. Apr 24, 2012 #1
    In my physics textbook, it states that the stopping distance increases with the square of the intial speed. Could someone provide me with an example of why this is true?

    Thank you

    For constant acceleration, how does distance relate to speed? (Look for a connecting kinematic formula.)

    Would it be the kinematic equation v^2 = vi^2 + 2a(x - xi) solved for delta x?

    Exactly. Vi would be the initial speed; V = 0, the final speed.
