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.
