The Physics Of Usain Bolt's Record-Breaking Sprint

The Physics Of Usain Bolt's Record-Breaking Sprint | Soccer | Scoop.it

In 2009, at the World Championships in Berlin, Usain Bolt beat his own previous world record by 0.11 seconds, running a 9.58-second 100-meter dash. The record is getting more and more difficult to break, as it's history shows (and as we may be nearing the limit of human speed), making each new record-breaking performance intriguing to physicists. A study, published today in the European Journal of Physics, examines the physics of Bolt's historic feat.

Stats:
Height: 6 ft 5 in.
Distance: 100m
Time: 9.58 seconds
Terminal Velocity: 12.2 m/s (27.3 mph)
Average Force: 815.8 newtons
Tailwind: 0.9 m/s (~2 mph)

Using approximate race-day conditions (temperature, altitude, Bolt's surface area) along with measurements from the race's laser velocity guard device (which measured Bolt's position and speed every 0.1 second), the researchers were able to calculate the immense amount of drag that Bolt overcame. Bolt used 81.58 kJ of energy during the race, but 92.21% of that energy was absorbed by the drag! Additionally, Bolt's maximum power output was 2619.5 watts after only 0.89 seconds of the race--more than enough energy to power a large vacuum cleaner (or the Pirate Bay).
