"This is the end of a great season for me," Montgomery said. "I knew I was in great shape and today everything was just perfect. The wind was perfect, my reaction time was almost perfect, but that is what you need to break world records."

if my math is correct, that works out to approximately 36.8 k/h or approximately 26 m/h if he hadnt of had to start from a dead stop.
i wonder what his finishing speed was?

Hi:
The typical process for a world class 100 meter dash is something like:
first ~30 meter accelaration;
then staying at top speed;
then slow down;
Some of the world best, such as Green, Lewis, can stay at the top speed longer, so it appears that they catch up by the end.
I read somewhere that the absolute maxim speed achieved by a sprinter is ~13m/s, by Canada's Donovan Bailey's at one point during his 1996 Olympic gold medal performance. Of course, by the time he finish, he is no longer that fast.
Is there a limit for 100 meter dash. Long time ago, when the world mark is 9.95, by Jim Hines. I heard the limit was 9.8x something, apparently, it is not true. But how fast will be the limit for mankind, any guess?

Here's the 10m break-down of Ben Johnson's and Carl Lewis's 100m at Seoul:
B.J. C.L.
1.83 1.89 10
2.80 2.96 20
3.80 3.90 30
4.66 4.70 40
5.50 5.65 50
6.33 6.48 60
7.17 7.33 70
8.02 8.18 80
8.89 9.04 90
9.79 9.92 100
This shows a maximum speed reached at about 40m and sustained until about 90m.
