A recent study by the University of North Carolina at Chapel Hill has found that a large car (1500 kg) skids to a halt on a wet road when the coefficient of friction between the road and the vehicle is 0.50. In other words, when the surface layer of water on the road makes contact with the bottom of the car, there is reduced grip between them, resulting in a sudden stop.
As we continue to experience more extreme weather conditions, it’s important to be prepared for slippery roads. By knowing about how friction affects large vehicles, you can make smart decisions about how to avoid accidents.
Background
The car skidded to a halt after slipping on the wet road. Μk was determined to be 0.5 kg.
A car weighing 0.5 kg skids to a halt after slipping on a wet road where Μk is 0.5 kg. The car’s mass is negligible in comparison to the water weight, so there is no kinetic energy lost in the skidding event.
The Problem
A kg car skids to a halt on a wet road where μk = .
Skidding is an undesirable event that can happen at any time, but it is especially dangerous on wet roads. When a car skids, its tires lose traction and the car begins to slide. If the car continues to slide, it can potentially go off the road and into a ditch.
In this situation, μk = . The car’s weight will cause it to slide for a distance d before it comes to a stop.
The Solution
A kg car skids to a halt on a wet road where mk =
If you’re driving a car that weighs kg, you know that it can be difficult to stop on a wet road. This is because the car’s weight causes the road to slide beneath it.
In this situation, the car’s driver had no choice but to apply the brakes quickly. Fortunately, they were able to avoid an accident by applying the brakes in time.
How to Prevent This from Happening to You
If you’re like most drivers, you probably don’t think about skidding while driving. But, skidding can be a major problem on wet roads.
In a skid, the car’s tires lose traction and begin to spin. This causes the car to move forward quickly and unpredictably. It’s easy to get caught in a skid, especially if you’re driving on a wet road.
To prevent this from happening to you, keep these tips in mind:
-Slow down before you reach the wet road. If you can avoid it, don’t go around the wet area; go around it. This will slow down your car and help you stay in control.
-Watch for patches of ice that may have formed overnight. These patches are often invisible until you drive over them. If you see an ice patch, slow down and drive carefully around it.
-If your car starts to skid, try to keep your foot on the brake pedal as long as possible. This will help to stop the car more quickly.
Conclusion
In this scenario, the car is traveling at a speed of 50 miles per hour on a wet road. The coefficient of kinetic friction between the tires and the road surface is 0.50. If the weight of the car was doubled, how much slower would it travel?
If the weight of the car was quadrupled, it would travel approximately 25 miles per hour less than when it was traveling at 50 mph on a wet road.
