Effective distance run = 100 m + (9.84 x 0.5) = 104.92
Effective speed = 104.92 m per 9.84 s
Therefore with no wind resistance, time to cover 100 meters = 100/104.92 x 9.84 = 9.3786 (9.38) seconds.
LOL:)
Wind speeds are not reported to two decimal places so the windspeed is probably meant to be 0.3 m/s. However here are the predictions for both wind speeds: -0.03 m/s : 19.62 (i.e. no difference)
-0.30 m/s : 19.60 Predictions when the wind speed is the max. allowable, i.e. 2 m/s are as follows: -0.03 m/s : 19.51
-0.30 m/s : 19.51
The real question is: If you ran the 100m in 9.69 in zero wind how fast would it be if you ran seriously to the end? I am 99.9% sure you refering to Usain Bolt 100m performance at the 2008 Olympic Games. Well you can't really ask that because Usain Bolt even with the wind would still be slowing down to (indirectly) Taunt? Celebrate? Asafa? I'm not sure but I am sure you can Expect Usain Bolt to run his Punas Out With Tyson Gay up to 100% this season.
10.08 to 10.10 thereabouts
A 1.7 m/s tailwind would improve his time by 0.08 seconds.
A 1.7 meter/second tailwind would aid the runner by .08 seconds. The adjusted time would be 9.70 seconds. Here's a link to use for wind and altitude adjustments: http://myweb.lmu.edu/jmureika/track/wind/index.html
19.89 seconds
The opposite of fast wind would be calm or still air.
The wind direction would be blowing to the north if it is going over your head while you stand south of the smoke stack.
If wind energy increases, wind mills will run more fast. More electricity will be produced.

This means that the runner/ jumper is running into a head wind of 6.1mph. To explain another way, the runner would not be assisted by the wind but running against it. If it said +6.1 the runner would have an advantage as the wind would be behnid them.
it travels three times as fast as a comet
As of 2021, the world record for the men's 100m is 9.58 seconds, held by Usain Bolt from Jamaica. For the women's 100m, the world record is 10.49 seconds, held by Florence Griffith-Joyner from the USA.
As fast as a hurricane with no doubt
