Two drivers each have a reaction time of 2.5 seconds. One is obeying a 90 km/h speed limit, and the other is travelling illegally at 108 km/h. How much distance will each of the drivers cover while perceiving/reaction to the need to stop, and what will the total stopping distance be for each driver (using practical stopping distance and assuming roadway grade g = -2.5%). Longitudinal friction coefficient (fi) can be calculated by the equation f = 1.0371 V-0.2729 where V vehicle speed in km/h.|
