Please note that the iOLab mass will be needed in many future labs and you should remember the procedure you've done here in order to repeat it for those labs. 01 Finding the Mass of the Device

9. Compare this to the known value of the mass. Please note that we have ignored friction. However, looking at your acceleration vs. time plot, you should be able to compare the magnitude of the positive acceleration peaks to the short time of negative acceleration that follows them. Comment on the comparison of these values. Be certain that your lab report contains a plot of the data zoomed to show all five peaks, as well as a plot showing the data zoomed to show a single peak. Show a neat table of your data

Be certain that your lab report contains a copy of the parametric plot, a table of (at least two) data points taken from the plot, and a good description of how you calculated slope. Finally use your data from all these sections to determine whether the masses are in agreement.
