1. Copy the table.
2. Calculate time elapsed squared (t2), record your results in the table.
3. Draw a graph distance traveled (s) on the y axis and time elapsed squared (t2) on the x axis.
4. Draw a line of best fit and calculate the slope of this line.
5. Write the equation of the line.
6. In your own words describe the equipment and set up you would use to perform this experiment, use a diagram to illustrate.
7. Cite reasons for errors in the results you would record from your experiment.
