Assuming it takes about 1.5 s for a driver having 0.02% alcohol in his/her system to react to a situation to avoid a collision. if such driver is traveling on a straight road at 50 mph, and the vehicle can decelerate at 2.5 ft/s2. determine the shortest stopping distance from the moment the driver see a pedestrian [hints: (a) convert miles per hour (mph) to ft/s.; (b) know that at stopping distance, final velocity is zero; (c) obtain initial distance before reaction].
