No - the stopping distance depends on the speed of the vehicle - it' not simply a case of 'doubling-up'.
As a vehicle's speed increases, its stopping distance will also increase. This is because the kinetic energy of the vehicle increases with speed, requiring more distance to come to a complete stop once the brakes are applied. Additionally, reaction time and road conditions can also affect stopping distance.

It increases faster than the speed increase ... approximately the square of the speed. So twice the speed results in 4 times the stopping distance.
The stopping distance is not straightforward and depends on two factors: The time for a driver to react to a situation called the "thinking distance". The distance travelled in between the driver realising he needs to brake and actually braking and during which the car carries on moving. The distance taken to stop once the brakes are applied called the "braking distance". Both these factors combine to make the total stopping distance, which is not a linear scale. Thus going twice as fast does not simply double the distance. Thus without knowing what the speed of the slowest car is we can not tell you "how much more distance to stop" at 20 mph the distance is 40 feet (under ideal conditions). at 30, 75 feet at 40, 118 feet at 50, 175 feet at 60, 240 feet at 70, 315 feet
Nothing. The freezing point depends on the molecular structure, not the volume of the substance. It will take a longer time to freeze twice the amount of liquid, but the freezing point remains the same.
On wet pavement, it will take your vehicle about twice as long to stop compared to dry pavement. This is due to reduced tire grip and increased distance needed for braking on wet surfaces. Drive cautiously and leave extra space between cars to account for longer stopping distances in wet conditions.
The distance between the above places is 4525 miles. This distance is point to point straight distance. The actual distance may vary according to the flight path chosen. Also this is not the airport to airport precise distance.
The diameter of a circle is twice its radius
The braking distance is proportional to the square of speed because as speed increases, the amount of kinetic energy that needs to be dissipated during braking also increases exponentially. This means that stopping a vehicle traveling at twice the speed will require four times the distance to come to a complete stop due to the increased kinetic energy that needs to be overcome.
You would do twice the work because work is calculated as force times distance. So, if you apply twice the force over the same distance, the work done would be twice as much.
At 60mph, it generally takes longer to stop compared to 30mph due to the higher speed and momentum. Factors such as reaction time, braking distance, and road conditions also affect stopping time. In general, stopping at 60mph will take more than twice the distance compared to stopping at 30mph.
Water has found its way to the inside of the brake cable, you may have to let the engine warm up for some time so that the exhaust will defrost it, as for history of this none for that car as far as I know but plenty of history with things freezing up in minus conditions.
