In 2009 Jamaican sprinter Usain Bolt set the world record in the 100-meter sprint at 9.58 seconds. For those of us more accustomed to sitting than sprinting, to translate this feat into terms of speed is to simply underscore the stunning nature of Bolt’s performance.
Speed is the rate at which an object (or person) moves through time. It is represented mathematically as speed = d/t (in which d is distance and t is time). That means that Bolt’s speed during his world-record run was 10.44 meters per second. Since many people are more familiar with automobiles and speed limits, it might be more useful to think of this in terms of kilometers per hour or miles per hour: 37.58 or 23.35, respectively. That’s faster than the estimated average traffic speed for the U.S. cities of Boston, New York City, and San Francisco. Even more astounding is the fact that Bolt started from a speed of zero and then had to accelerate, which means that his top speed actually was faster.
In 2011 Belgian scientists used lasers to measure Bolt’s performance in the different stages of a 100-meter race held in September that year. They found that, 67.13 meters into the race, Bolt reached a top speed of 43.99 kilometers per hour (27.33 miles per hour). He finished with a time of 9.76 seconds in that race, but research has suggested that, with his body type, he probably shouldn’t even be competitive at that distance. From a biomechanical perspective, the fastest sprinters are relatively short, and their muscles are loaded with fast-twitch fibers for rapid acceleration. The elite sprinter is a compact athlete, not a tall and lean one. Given his size—literally head and shoulders above the other competitors—Bolt should be last off the blocks and last across the finish line. And yet he is the fastest man in the world.
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.
The average sprinting speed for many athletes is 24km/h (15mph). So getting a speed of 20.5 or even 20 mph on the dot is something not everyone can achieve. Therefore, your sprint speed is pretty fast.
Weyand's team calculated that humans could theoretically run as fast as 35 or 40 miles per hour, based on our gait and the maximum forces our muscles can generate.
The Outright Land Speed Record, which currently stands at 763.035 mph(1227.985 km/h), is the most prestigious, but there are hundreds of other records in myriad classes based on factors such as engine type and capacity, weight or body shape.
To date, the fastest a human has been recorded running is Usain Bolt's 2009 record-smashing 100-meter dash. There, he briefly reached a top running speed of 27.78 mph.
The human frame is built to handle running speeds up to 40 miles per hour, scientists say. The only limiting factor is not how much brute force is required to push off the ground as previously thought, but how fast our muscle fibers can contract to ramp up that force.
That means that Bolt's speed during his world-record run was 10.44 meters per second. Since many people are more familiar with automobiles and speed limits, it might be more useful to think of this in terms of kilometers per hour or miles per hour: 37.58 or 23.35, respectively.
Usain Bolt. The Jamaican sprinter is the fastest human alive, our reality's version of the Flash. He set a world record in 2009 at the 100 meter sprint at 9.58 seconds. His top speed was 27 mph.
Top Speed. At the Berlin 2009 World Championships, Bolt set a world record time of 9.58 seconds for the 100m race, notching a top speed of 27.8 miles per hour (44.72 kilometers per hour) between meters 60 and 80, with an average speed of 23.5 mph.
However, while Lyles is currently the fastest runner in the world, he doesn't hold the record for the fastest 100 meter. That belongs to Usain Bolt, and Lyles has his eyes — and fleet feet — on breaking Bolt's longstanding records in the 100 meter and 200 meter events.
Changes in speed are expressed in multiples of gravitational acceleration, or 'G'. Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two.
The most obvious answer appears to be light. In a vacuum, light travels approximately 186,000 miles per second (300,000 kilometers per second). Nothing in the universe that we know of can exceed this speed.
For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).
Nasa's Parker Solar Probe has once again broken its own record for being the fastest man-made object ever. The history-making craft reached a ferocious 394,736 miles per hour (635,266 km per hour) as it continues its mission hurtling around the Sun.
The crew of NASA's Apollo 10 moon mission reached a top speed of 24,791 mph (39,897 kph) relative to Earth as they rocketed back to our planet on May 26, 1969. That's the fastest any human beings have ever traveled.
Al Joersz is fitted into a special suit needed to fly at high speeds. Then Capt. Joersz, pilot-in-command, and Maj. Morgan, reconnaissance systems officer, pose in front of an SR-71 after breaking the air speed record by flying 2,193.167 miles per hour at Beale Air Force Base, California on July 28, 1976.
Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested. Mach 10 has, however, been achieved by a spacecraft - on November 16, 2004, NASA launched the X-43A, an air-breathing hypersonic vehicle, and was able to reach real Mach 10 while being pushed into the atmosphere.
