The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
The record is 44.72 km/h (27.78 mph), measured between meter 60 and meter 80 of the 100 meters sprint at the 2009 World Championships in Athletics by Usain Bolt. [4] [5] (Bolt's average speed over the course of this race was 37.578 km/h or 23.35 mph.) [6] Compared to quadrupedal animals, humans are exceptionally capable of endurance, but incapable of great speed. [7]
A car travelling at 50 km/h generally goes for less than one hour at a constant speed, but if it did go at that speed for a full hour, it would travel 50 km. If the vehicle continued at that speed for half an hour, it would cover half that distance (25 km). If it continued for only one minute, it would cover about 833 m.
In the rest of the world, 0 to 100 km/h (0 to 62.1 mph) is used. Present production model performance cars are capable of going from 0 to 60 mph in under 5 seconds, while some exotic supercars can do 0 to 60 mph in between 2 and 3 seconds. Motorcycles have been able to achieve these figures with sub-500cc since the 1990s. [1]
New Zealand's John Walker, who with a 3:49.4 performance in August 1975 became the first man to run the mile under 3:50, ran 135 sub-four-minute miles during his career (during which he was the first person to run over 100 sub-four-minute miles), and American Steve Scott has run the most sub-four-minute miles, with 136.
"You get a lot more muscle recruitment overall when you run faster than when you run slower (for longer)," says McGrath. This works the fast-twitch muscle fibers, which help for quick movements.
It’s a good idea to use one if your car is parked in the sun. This will protect your dashboard from melting or cracking. A new windshield shade can go for $15 to $20, which is much cheaper than ...
Since one-foot rollout before the timer starts is used by some North American publications, times which exclude the time of the first foot of acceleration are included. [1] [2] [4] All times are independently tested and verified.
