5. Tests reveal that a normal driver takes about 0.75 s before he or she can react to a situation to avoid a collision. It takes about 3 s for a driver having 0.1% alcohol in his system to do the same. If such drivers are traveling on a straight road at 30 mph (44 ft/s) and their cars can decelerate at 2 ft/s², determine the shortest stopping distance d for each from the moment they see the pedestrians. Moral: If you must drink, please don't drive! 44 ft/s

5. Tests reveal that a normal driver takes about 0.75 s before he or she can react to a situation to
avoid a collision. It takes about 3 s for a driver having 0.1% alcohol in his system to do the same.
If such drivers are traveling on a straight road at 30 mph (44 ft/s) and their cars can decelerate
at 2 ft/s², determine the shortest stopping distance d for each from the moment they see the
pedestrians. Moral: If you must drink, please don't drive!
v₁ - 44 ft/s
