It is known that the braking distance of a car depends on many different factors. But there is also a universal formula that allows you to easily calculate it: just plug in the required values, and you're done!
The braking distance of a vehicle is the distance that a vehicle travels from the moment the braking system is applied until it comes to a complete stop. The length of the braking distance directly depends on the speed of the vehicle, the method of braking, as well as road conditions. For example, at a speed of 50 km / h, the average stopping distance will be approximately 15 m, and at 100 km / h - 60 m.
Please note that the braking distance of a car depends on many factors, such as: speed, weight of the car, road surface, weather conditions, braking method, as well as the condition of the wheels of the car and its braking system.
Determine the braking distance of the car according to the following formula: S = Ke x V x V / (254 x Фs), where
S - braking distance of the car in meters, Ke is the braking coefficient, which is equal to 1 for a passenger car, V - vehicle speed (in km / h) at the beginning of braking, Фc - coefficient of adhesion to the road (different indicators depending on weather conditions), 0.7 - dry asphalt, 0.4 - wet road, 0.2 - rolled snow, 0.1 - icy road.
Note that there are several different methods of braking, namely smooth, sharp, stepped and intermittent. Use gentle braking in a calm environment. Increase the pressure on the brake pedal gradually to ensure a smooth decrease in vehicle speed. It is with this method of braking that you get the longest stopping distance.
Remember that hard braking when you press hard on the brake pedal will usually cause the wheels to lock, which can lead to loss of control and skidding of the vehicle. If you choose step braking, then press the pedal several times, but each subsequent press do with great force, and so on until the car comes to a complete stop. In intermittent braking, press the pedal hard, almost until the wheels lock, and then release the pedal. Follow the same principle until the vehicle comes to a complete stop.
