a) A world record was set for the men's 100 m dash in the 2008 Olympic Games in Beijing by Usain Bolt of Jamaica. Bolt coasted across the finish line with a time of 9.69 s. If we assume that Bolt accelerated for 3.00 s to reach his maximum speed, and maintained that speed for the rest of the race, calculate his maximum speed and his acceleration. Umaz= a= b) During the same Olympics, Bolt also set the world record in the 200 m dash with a time of 19.30 s. Using the same assumptions as for the 100 m dash (that is, it took him 3.00 s to reach maximum speed), what was his maximum speed for this race?
