The starting point of Usain Bolt versus sports cars
On the fifth of August, the opening ceremony of the 2016 Summer Olympics in Rio de Janeiro, Brazil takes place. The attention of the whole world of sports will be focused on the first South American edition of the tournament.
A special highlight in track and field is the 100-meter dash. Decided in below ten seconds, there is still an enormous amount of adrenaline being discharged on this short track. One name receives particular attention in this discipline: Usain Bolt.
The Jamaican sprinter is called Usain St. Leo Bolt with his full name and is decorated with various awards from the Olympics to world championships to world records. He is the sole person to run the 100-meter dash with a time of below 9,6 seconds, 9,58 to be precise.
But how effectively can the exceptional sprinter Bolt stand his ground in comparison to powerful sports cars? The ES Magazine made some calculations.
Usain Bolt achieved his world record in the 100-meter dash in 9,58 seconds. He accelerated with 9,5 m/s2 and reached a top speed of 43,92 km/h. He generated 3,5 horse power and a power to weight ratio of 26,587 kilograms per horse power (kg/HP).
The air drag coefficient was 1,2. Only 7,79% of the energy Bolt released during the sprint was effectively used for the acceleration. All other energy dispersed because of the large aerodynamic drag.
