Since that memorable day at the Beijing 2008 Olympics, a big question has been, “What would the 100 m dash world record have been had Usain St Leo Bolt not celebrated at the end of his race?”
How fast would Bolt have run if he had not celebrated the last 2 s?
This question was considered recently in a general science course entitled Sport Science; the analysis is presented below. Prior to considering this question, students studied basic physical quantities such as speed, velocity, and acceleration. Students also read from work by Hoffman
Stride: A long step in Walking or Running.
Firstly, let's look at his attributes:
Height: 6ft 5Inches
Average Stride Length: 2.44 mts
Average Stride Frequency: 4.23 strides/seconds
Average Speed: 10.3 m/s
Beijing Olympics 2008:
Splits and times for 20 m intervals
Reaction time: 0.165
Tail Wind: Not found
Peak Speed: 43.88 km/hr
20-40 mts: 1.78s
40-60 mts: 1.67s
60-80 mts: 1.64s
80-100 mts: 1.73s
First individual to create a record of 9.69s
IAAF World Athletics Championships 2009, Berlin :
Splits and times for 20 m intervals
Reaction time: 0.146s
Tail Wind: 0.9 m/s
Peak Speed: 44.72 km/hr
20-40 mts: 1.75s
40-60 mts: 1.67s
60-80 mts: 1.61s
80-100 mts: 1.66s
Thus creating a world record of 9.58s after an year of a record of 9.69s. He broke his own record.
By estimating Reaction time of 0.148s
and adjusting the frames per seconds by 60 and cutting off the celebration timing of 0.05 seconds, he would have probably made around 9.56 to 9.61 seconds which would have been a mesmerizing record and it will take years for the humankind to beat this record.
