1. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12ft/s^2. It takes the driver of car A 0.75 to react. When he applies his brakes he decelerates at 15ft/s^2. Determine the minimum distance d between the cars so as to avoid a collision.
