Car B is traveling a distance d ahead of car A. Both cars are travelling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s^2. It takes the driver of Car A 0.75 seconds to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 15 ft/s^2. Determine the minimum distance d between the cars so as to avoid a collision. a. 15.0 ft b. 20.3 ft c. 16.9 ft d. 12.1 ft
