In 2019, in the Russian Federation, traffic police created a survey for car enthusiasts, which showed that more than 80% of people do not know how to calculate their braking distance. This article was created in order to understand how to make calculations correctly.
Interview
About 83% of all drivers in the Russian Federation really do not know how to calculate their braking distance at a speed of 60 km / h. The rest (17%) are able to do this. Yes, it may be difficult. However, this is precisely why this article was created.
In the survey, car owners were asked to answer several questions regarding the topic of braking distance. In this survey, it is worth noting that more than 30 thousand people took part. Of these, 83% of people were unable to answer correctly. The exact stopping distance at a speed of 60 km / h is approximately 45 meters.
Calculation
If you listen to official data and sources, then an average car and a normal driver with an average reaction will need from two to three and a half seconds to a complete stop at a speed of 60 km / h. And at this time, not only the time of fully depressing the brake pedal is turned on, but also the reaction to the appearance of an obstacle, as well as the transfer of your foot from the gas pedal to the brake.
In one second, a car with a speed of 60 kilometers per hour overcomes 16 meters. Therefore, if you make your braking distance ideal, then its distance will be at least 45 meters. However, this is at best. At worst - 55-60.
Fact
According to scientists, the driver’s response to the obstacle is one second. During this time, the car will travel 16 meters at a speed of 60 kilometers per hour. The braking distance itself at this speed will require at least another 16 meters (according to the laws of physics). Therefore, the minimum distance will be 32 meters. But still, calculations are one thing, and practice is another.
In everyday life in real conditions it is almost impossible to achieve such an effective braking. However, it is possible. Moreover, all calculations are made in such a way that the driver looks carefully at the road and around. And if you are in an emergency, smoke, chat on the phone or switch the radio - this can not be discussed. In such cases, the braking distance is critical, and in many cases you simply will not stop, or you will do it after you knock someone down.
Percentage ratio
50% of all survey participants said that only 30 meters would be enough to completely stop the car. However, this is not at all how it became clear in the material of this article.
30% replied that 10 meters was enough. Yes, such an indicator, in general, is unrealistic. For such a short period of time (less than a second, under the best conditions), the driver will not even have time to react, not like pressing the brake pedal. We are not talking about a complete stop. Therefore, if you really assume that the stopping distance from 60 kilometers per hour is only 10 meters, then you would rather beat a person to death than stop.
Only 10% of all survey participants replied that the distance would be 80 meters. Yes, in practice, this is possible. However, most often, such a long way is for cars with bad brakes, on a snowy road and for drivers with complications (poor eyesight, reaction, etc.)
The last 10% chose the option of 45 meters. It was they who remained right - it is such a stopping distance at a speed of 60 km / h that you need to completely stop your car. And so it became clear how in the Russian Federation drivers are not able to calculate such simple mathematical problems.
Some people think that it’s not at all important to drive on public roads. And someone thinks differently - if you do not know the basics, then you should not drive a car. And yet, those people who believe that the vehicle can brake at a speed of 60 kilometers per hour for 10 meters have remained wrong. This may be, however, not in real conditions. Only in games or in dreams. Let the braking distance of a car at a speed of 60 km / h be 10 meters, however, only under one condition - if your car does not comply with all laws of physics.
Conclusion
In this article, a topic was dealt with concerning the physics of the motion of a machine. It became clear what the correct answer was in the very poll that the traffic police created. And most importantly, the main question was addressed in the material: what is the braking distance at a speed of 60 km / h in a car.
