A sample of data that you might collect is plotted below. The pusher's hand lost contact with the IOLab device somewhere before the negative flat line, but it's not clear exactly where. Here are three hypotheses about the data:

• Hypothesis A: The pushing hand lost contact with the IOLab at the top of the acceleration peak.
• Hypothesis B: The pushing hand lost contact with the IOLab when the acceleration became zero.
• Hypothesis C: The pushing hand lost contact with the IOLab when the acceleration got to its lowest value.
