Organic acids are of two types. One has the COOH group (the carboxyl group). An example is acetic acid (CH3COOH), the acid in vinegar. It is made by oxidizing grain alcohol or by the fermentation of the fruit sugar in cider. The other type has a phenol group, as in phenol (C6H5OH).
Calculate the total braking distance. This formula is 1/2 the initial velocity in feet per second multiplied by the time required to stop, which is 0.5 x 102.7 x 5.135 = 263.68. The calculated thinking distance is 2 x 102.7 = 205.4. Add the two numbers together. 469.08 feet is the total braking distance.
At 20 mph: Reaction Distance of 31 feet + Braking Distance of 36 feet = Stopping Distance of 67 feet. This means that if you are traveling at only 20 mph, you have to allow 67 feet of stopping distance for your vehicle after recognizing a hazard. At 40 mph. Your Reaction Distance is 83 feet and your Braking Distance is 152 feet, resulting in a Stopping Distance of 235 feet. At 60 mph.
