a=v/t= the second runner dash with 9.76 seconds so no, he will not be able to break the record.

Is this right?

**drwls**, Saturday, February 4, 2012 at 10:01pmIf the second runner can continue to accelerate at 1.07 m/s^2 from a standing start, after 9.58 seconds he will travel

(1.07/2)*(9.58)^2 = 49.1 m, and he will be very far behind when Bolt completes the race.
