Human reaction times are worsened by alcohol. How much further (in feet) would a drunk driver’s car travel before he hits the brakes than a sober driver’s car? Assume that both are initially traveling at 50.0 mi/h and their cars have the same acceleration while slowing down, and that the sober driver takes 0.33 s to hit the brakes in a crisis, while the drunk driver takes 1.0 s to do so. (5280 ft = 1 mi)
