Tests reveal that a normal driver takes about 0.75 s before he orshecan react to a situation to avoid a collision. it takes about 3 sfora driver having 0.1% alcohol in his system to do the same. ifsuchdrivers are traveling on a straight road at 44 ft/s and theircars can decelerate at 2 ft/s^2, determine the shortest stoppingdistanced for each from the moment they see the pedestrians.
