If no brakes are used immediately, an automobile with a starting velocity of 30 mph or 44 feet/s will collide with a person. If the driver is inebriated, he or she will be able to respond to the situation in three seconds. If the driver is not intoxicated, he or she can react for about 0.75 seconds. Determine the shortest stopping distance required for the driver (intoxicated, under influence of alcohol) to break on time if the automobile accelerates at -2 feet/s2. *
