This depends heavily on the vehicle in question. Stopping distance is a function of the mass of the vehicle, the width of the tires (i.e. friction area in contact with the pavement), and the type and "strength" of the brakes on the vehicle.
A typical mid-size sedan like a Toyota Camry can stop in roughly 30 feet from 30mph. A large SUV like a Ford Explorer requires about 35-40 feet, while a Semi-Tractor trailer cab with loaded trailer can stop in about 40 feet, despite weighing over 10 times that of the SUV, since it has much more powerful brakes and much more wheel contact area.
The stopping distance, after decelerating from 60 mph to 0 mph, will depend on the efficiency of the brakes, the friction between the tyres and the road surface and the mass of the vehicle.The initial speed alone cannot give you an answer.
In the case of constant speed: distance = speed x time. Or, Total distance = Average speed * Total Time
Average Speed = Total Distance/Total Time.Instantaneous Speed = Derivative of Distance with respect to Time.
The average speed is the total distance divided by the time taken to cover the distance.
Mean Speed = Total Distance / Total Time taken to cover the distance
The total stopping distance for a car travelling at 30 mph on a dry surface is about 75 feet. However, you may wish to note that in most countries, driving a car on the pavement is illegal.
That depends on type of vehicle, vehicle condition, weight in or being towed by vehicle, tire condition and model, ABS equipped? all sorts of things.
With increased speed, stopping distance increases.
Stopping distance also increases.
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
It increases faster than the speed increase ... approximately the square of the speed. So twice the speed results in 4 times the stopping distance.
3 seconds behind him, no matter the speed on dry pavement. More on wet pavement.
using the formula, speed squared divided by 20 plus speed gives 40 feet approximate stopping distance at 20mph.
The stopping distance, after decelerating from 60 mph to 0 mph, will depend on the efficiency of the brakes, the friction between the tyres and the road surface and the mass of the vehicle.The initial speed alone cannot give you an answer.
No - the stopping distance depends on the speed of the vehicle - it' not simply a case of 'doubling-up'.
No it decreases it.
The distance needed to stop also increases.
