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
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
The force of gravity is proportional to the mass, and inversely proportional to the SQUARE of the distance between them. If we double the mass at the same distance, we double the force; if we double the distance, the force is cut to one-FOURTH. So twice the mass and twice the distance; the force will be (800*2)/2^2, or 400.
it's frequency is 2 hertz
Yes. Meg is short for megabytes per second (mbps) so it is twice as fast
It increases faster than the speed increase ... approximately the square of the speed. So twice the speed results in 4 times the stopping distance.
Twice Second was created in 2005.
With increased speed, stopping distance increases.
Distance is how far you have traveled. For example, if you walk to school and back, you will have traveled twice the distance between the school and your home. Displacement is how far you have gone in your travels. For example, if you walk to school and back, your displacement is zero because you end up where you started.
Twice half its length! What are the chances of having some good luck with a lepricorn, odds say 50:50 the rule of 3rds say 30%!
32 miles per hour. The speed at which the car is travelling is the distance in miles that the car travels per hour. If the car travels 16 miles in 30 minutes it should then travel twice as far in one hour, since one hour is twice as long as 30 minutes (half an hour). So, the car travels 2 * 16 miles per hour, which equals 32 miles per hour.
Sound pressurefalls inversely proportional to the distance 1/rfrom the sound source.At the double distance there is half of the sound pressure or -6 dB of the sound pressure level.Sound travels at a finite speed (around 343 m/s at 20°C) at double the distance it takes twice as long to arrive.
A minim note is twice faster than a semibreve.
