m = metres, / = per, s = second, km = kilometer, hr = hour

4. On the same line graphs illustrate Tim and Usain performance results.

For the following:

Displacement (m) - Cumulative Time (s)

Displacement (m) - Velocity (m / s)

Displacement (m) - Velocity (km / hr)

Displacement (m) - Acceleration (m / s / s)

*Ensure that all of your graphs are Titled, have appropriate Scaling, Units, & Axes Labels

*Ensure that all of the Displacement axes begin at 0 metres

5. Provide 1 comment / observation for each of the graphs (select one of the

Displacement - Velocity graphs only) which could be specific to your results or

Usain's results, or a comparison / contrast of your performance with that of Usain's Bolt (minimum 3 comments in total).

6. Provide informed reasons (minimum 3) for the profile of Usain's results using both biomechanical & physiological perspectives.
