It depends on many variables, vehicle type, it's weight, tires, weather, road material( gravel, blacktop, concrete, driver reaction time. A good general rule of thumb is to leave 1 1/2-2 car lengths per 10mphs. An example: 9-12 car lengths at 60 mph. It might seam like alot but at that speed you travelling 88 ft/sec. The average family sedan requires 130ft to stop from 60mph(the average sedan being 16ft +/- =8.1 length leaving 12ft to spare). That is assuming you brake instantly, the 2 car lengths would give you a "1/2 a second" to react, which I think everyone would say it's much. With bad weather rain,snow,fog that should double or triple.
The stopping distance of a car increases.
It means the minimum distance the car moves between the time the driver decides to stop and the time the car actually stops. The distance can never be zero, and any pedestrian or animal who happens to be crossing in front of the car at a distance less than the stopping distance is simply out of luck.
Stopping distance also increases.
Total stopping distance is the thinking distance (The distance it takes for your brain to process the event and decide to stop the car) and the stopping distance (The distance it takes to stop the car once deceleration has begun) added together.
The greater the mass of the car and its occupants the longer the stopping distance that is required for the vehicle. Stopping distance is calculated by taking into account car mass and reaction time in braking
The stopping distance at 55 mph varies based on factors like vehicle type, road conditions, and braking efficiency. On average, it takes about stopping distance of stopping distance of 200-250 feet to come to a complete stop, which includes both the reaction distance (the distance traveled while the driver reacts) and the braking distance. If you consider a reaction time of about 1.5 seconds, this adds roughly 120 feet to the total stopping distance.
Total stopping distance is the thinking distance (The distance it takes for your brain to process the event and decide to stop the car) and the stopping distance (The distance it takes to stop the car once deceleration has begun) added together.
The stopping distance of a car can be determined by considering the car's speed, reaction time of the driver, and the braking distance required to come to a complete stop. The stopping distance is the sum of the reaction distance (distance traveled during the driver's reaction time) and the braking distance (distance traveled while the brakes are applied). It can be calculated using the formula: Stopping distance Reaction distance Braking distance.
To calculate the stopping distance, we need more information such as the mass of the car and the acceleration. The force alone is not sufficient to determine the stopping distance.
Friction plays a key role in determining the stopping distance of a toy car rolling down a surface. The greater the friction between the wheels of the car and the surface, the shorter the stopping distance will be. Conversely, if there is less friction, the stopping distance will be longer. Other factors such as the speed of the toy car, the weight of the car, and the surface roughness will also influence the stopping distance.
The stopping distance can be calculated using the equation: stopping distance = (initial velocity^2) / (2 * deceleration). The deceleration can be calculated using the formula: deceleration = force / mass. Plugging in the values and calculating will give you the stopping distance.
If the speed of the car becomes NV, with N > 1, the minimum distance it can be stopped over remains the same at S. This is because the stopping distance is primarily determined by factors like initial speed, braking capacity, and road conditions, rather than the multiple of the speed.
