Final answer:
The best world record mentioned is Usain Bolt's 9.58 seconds in the 100 meter dash set in 2009, with an average speed of 10.4 m/s or 23.4 mph. His performance showcases significant acceleration and maximum speed, emphasizing his status as the fastest man in history.
Step-by-step explanation:
World Record in 100 Meter Dash
The best world record in the men's 100 meter dash was set by Usain Bolt in 2009 with a time of 9.58 seconds. During this extraordinary performance, Usain Bolt's average running rate was 10.4 m/s, or 23.4 mph. This remarkable achievement not only set a new world record but also demonstrated the incredible physical capabilities of Usain Bolt, who is widely considered to be the fastest man in history.
Usain Bolt's Acceleration and Maximum Speed
In the 2008 Olympic Games, Usain Bolt set a world record in the 100-m dash with a time of 9.69 seconds. Assuming he accelerated for the first 3 seconds, his maximum speed and acceleration had to be immense to achieve this record. If we use physics to calculate these figures, we can better understand the phenomenal athletic prowess demonstrated by Bolt.
Other World Records
In addition to Usain Bolt's records, we have information on other notable world records like that of New Zealander Burt Munro, who set a record for an Indian motorcycle on the Bonneville Salt Flats in Utah. He achieved a maximum speed of 183.58 mi/h.
