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.
Worth noting is that from 50 to 100 kph the braking distance of a car will increase from 10 metres to 40 metres. When you double the speed of a car braking distance quadruples. This is based on the laws of physics. When a car is moving it has kinetic energy, Â½mv2.
