Please solve the problem asap using the correct method
2. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 ft/s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 ft/s². It takes the driver of car A 0.75 s to reach (this is the normal reaction time for drivers). When he applies the brakes, he decelerates at 15 ft/s². What is the minimum distance (d) between the drivers to avoid a collision. 14
