Norwegian physicist -Bolt could run 100-metre in 9.55

A Norwegian physicist said Usain Bolt could have run the 100-metre Olympic final in 9.55 seconds if he had not slowed down to celebrate winning gold.



Hans Eriksen said he estimates that Bolt could have finished the race in a time between 9.55 and 9.61.



Bolt won the final at the Beijing Olympics last month in 9.69 seconds, shaving 0.03 seconds off the previous record he set in May.



Eriksen, a physicist at the Institute of Theoretical Astrophysics at the University of Oslo, said he got the idea to examine just how quick Bolt could have gone after hearing his coach say that the Jamaican could have run 9.52 seconds.



Eriksen and his colleagues analysed TV footage of the race, focusing on Bolt\'s position, speed and acceleration, as well as that of runner-up Richard Thompson.
