Transcript of Problem #: 2006B2

Word Problem
A world-class runner can complete a 100 m dash in about 10s. Past studies have shown the runners in such a race accelerate uniformly for a time
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
and an approximate value of
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.
Materials needed for experiments
Tape measures
Starter's pistol
Step #1
Set up a table of the runner's names and how long it takes them to run 100 meters.
Chart needed to track results in conducted experiment
Step #2
Lay out the measuring tape to equal the length of 100 meters.
Step #3
Shoot the starter pistol and began to time each runner individually, to get the correct times for each one.
Step #4
After getting all the times for each runner, divide each time t by the distance of 100 meters, to find the rate of velocity. Then divide the change in velocity by time again to find
Uniform Acceleration
Uniform acceleration will occur during the whole race-- with the hope that every runner runs at a constant rate of velocity.
You would calculate this by dividing the time by the distance traveled, or
