I. Data Analysis
1. Fill in the table below with the data you collected for 5 different starting heights. [Remember, each data point is
an average of 4 runs from the same height.]
2. Compute the averages and standard deviations of the values you will be plotting for your best-fit line graph, and
include them at the bottom of the table.
3. Plot the data points and the error bars (or, if using software, you can plot the points that represent the endpoints of
the error bars) on a graph. You have the same alternatives as the previous lab at your disposal for making this plot:

4. Draw a conclusion about whether the author's theory is confirmed or refuted by the data.
II. Questions
5. Assume for a moment that the author's theory is correct. In this case, what physical properties of the system do the
slope and intercept of the line represent?
6. Discuss any issues that you feel need to be addressed regarding the physics behind this experiment.
