Olympic spring Usain Bolt set the world record in the 100 meter dash with a time of 9.58 seconds. The physics behind his performance are impressive. Physicists have modeled his position as a function of time to be as follows:"

where A=110 m/s, B=12.2 m/s, k=0.9 1/s. Using this information, find his acceleration when t = 0 seconds. If his mass was 86 kg at the time of the race, what was his force at t = 0 seconds. What was the force from the ground on Bolt at t = 0 seconds?
