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.
Outline the procedure that you would use to determine au and tu, also a label diagram of experimental setup
