Braking and Reaction Time A driver/operator should know the total stopping distance for a particular fire apparatus. The minimum length of crest vertical curves should be the greater of: a. Under normal circumstances, the time it takes a driver to get their foot to the brake pedal is relatively short. Riders can put themselves at an advantage by thinking about how to improve behavior and performance in each of the three parts. The stopping distance at 60 mph (292 feet) is more than 44 percent longer than the stopping distance at 50 mph (221 feet) even though 60 mph is only 20 percent faster than 50 mph. As is the expectation value of the rate of energy loss per unit distance through collisions, represents, correspondingly, the expectation value of the particle's range. 37 terms. 21.
