A world-class runner can complete a 100 m dash in about 10 s. Past studies have shown that runners in such a race accelerate uniformly for a time tu and then run at constant speed for the remainder of the race. A world-class runner is visiting your physics class. You are to develop a procedure that will allow you to determine the uniform acceleration au and an approximate value of tu for the runner in a 100 m dash. By necessity your experiment will be done on a straight track and include your whole class of eleven students.

c. Outline the process of data analysis, including how you will identify the portion of the race that has uniform acceleration, and how you would calculate the uniform acceleration.

2. Relevant equations

x=1/2 a(t)^2

3. The attempt at a solution

I tried using the equation above, but I'm not exactly sure how to explain the process of data analysis or how to identify the portion that has uniform acceleration

I'm not actually supposed to solve the equation, I just have to describe how you would go about solving it by using a description defining all variables being used, description showing how the needed variables (acceleration or final velocity) will be determined, and a transformation of the description into equation form

The thing that I am having trouble with is explaining my answer. I have to include all of the information above^^^
