12. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 "/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 2.lt 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 /2. Determine the minimum distance d be tween the cars so as to avoid a collision. (Practice at Home)
