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.
