Compute each part of given question:

Question: An Olympic sprinter competes in 100m dash. The runner accelerates from rest to maximum speed at a constant rate during the first 3s, and completes the race in 10.29s.

Part A: What are the accelerations and maximum speed of the sprinter?

m/s2

m/s

Part B: The sprinter wants to estimate the time to run a 200m dash. Assuming the same acceleration and maximum speed as in part (a), determine the time required to complete the race. The present world record (as of 2013) is 19.19s.

s

Please do a step by step solution since I'm kind of lost with this question.
