Q1 Car B is traveling a distance d ahead of car A. Both
cars are traveling at 80 ft/s when the driver of B suddenly
applies the brakes, causing his car to decelerate at 10 ft/s?. It
takes the driver of car A 0.65 s to react (this is the normal
reaction time for drivers). When he applies his brakes, he
decelerates at 17 ft/s?. Determine the minimum distance d
be tween the cars so as to avoid a collision.
