The minimum distance required to stop a car

  1. Oct 11, 2007 #1
    The minimum distance required to stop a car moving at 44.0 mi/h is 42.0 ft. What is the minimum stopping distance for the same car moving at 77.0 mi/h, assuming the same rate of acceleration?

    how do i go about doing this problem.? pls help.

    Well, you need to find out the acceleration of the first car. Do you know a formula that relates acceleration to velocity and time?
