A sprinter running a 100 m dash leaves the starting block and accelerates to a maximum velocity of 11m/s at 6s into the race. The sprinter maintains this velocity for 2s, and then slows down until crossing the finish line 11s after beginning the race.
a) What was the sprinter's average acceleration during the first 6s of the race?
b) What was the sprinter's average acceleration form 6-8s into the race?
