what equations should i use for these problems

a) A world record was set for the men's 100m 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. If we assume that Bolt accelerated for 3.00 to reach his maximum speed, and maintained that speed for the rest of the race, calculate his maximum speed and his acceleration. b) During the same Olympics, Bolt also set the world record in the 200 m dash with a time of 19.30s. Using the same assumptions as for the 100m dash (that is, it took him 3.00s to reach maximum speed), what was his maximum speed for this race? m/s
