Question

Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 m/s when the
driver of B suddenly applies the brakes, causing his car to decelerate at 12 m/s 2 . It takes
the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he
applies his brakes, he decelerates at 15 m/s 2 . Determine the minimum distance d between
the cars so as to avoid a collision.
