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.
Thinking, braking and stopping distance. To be a safe driver you need to understand the factors that affect a car's stopping distance. The stopping distance depends on two factors: 1  Thinking distance-It takes time for a driver to react to a situation.2  Braking distance-The braking distance is the distance taken to stop once the brakes are applied.he stopping distance depends on two factors: 1  Thinking distance-It takes time for a driver to react to a situation. 2  During this reaction time the car carries on moving.
