You can calculate the braking distance, that is, the distance that the car will travel from the beginning of braking to stopping, using simple formulas. For many drivers, this information will be very helpful.

Instructions

Step 1

The braking distance of a car is directly dependent on several factors. These include: the speed of the car, its weight, the chosen method of braking, the surface of the road, the presence of water or ice on it. If you are driving at a speed of 100 kilometers per hour, then the stopping distance can be 55-60 meters. It is clear that poor brakes or "bald tires" can increase the stopping distance.

Step 2

To accurately calculate the stopping distance, you can use the following formula: S = Ke x V x V / (254 x Фs). Symbols in it mean the following: S - braking distance, calculated in meters; Ke - braking coefficient (for cars it is equal to one); V is the speed (km / h) with which the car was moving when braking began; Фc is the coefficient indicating the adhesion of the car's wheels to the road surface. Here, under different weather conditions, the values can change, and are: 0.7 - dry asphalt road; 0.4 - wet asphalt road; 0.2 - road covered with rolled snow; 0.1 - road covered with a layer of ice. It can be seen that the highest coefficient is when driving on dry road, that is, in optimal driving conditions.

Step 3

The longest braking distance occurs when braking is applied by gradually increasing brake pressure. In addition, there are several other types of braking. You can brake smoothly, sharply, stepwise and intermittently.
