What you should do: Design an experiment to test each of the three hypotheses A, B, and C using information from a second sensor (there are several that you can use}. Your experiment should address the following: I How does the data from the second sensor tell you the pusher's hand has lost contact? I How will you compare results between the sensors to test the hypotheses? Your experiment should identify the points corresponding to hypotheses A, B, and C on your own acceleration plot and the time when the pusher's hand has lost contact on the second sensor's plot. We suggest two ways to compare the results: 0 Find the values of the second sensor measurements that happen at the same time as points A, B, and C on the accelerometer plot. Compare these measurements to your criteria for "lost contact."
