1. Compare the energy of your ball as a function of bounce number by plotting ?/?K/m vs Bounce Number for both surfaces. Bounce Number 1 will refer to the information between impacts 1 and 2; the first row of data in your table from 2.2. Plot both data sets on the same graph, making sure to use different shapes and/or colours to differentiate your data sets. Submit your single plot containing both data sets with the appropriate axis labels and a legend (do not connect data points).
