Question

Andre recorded the movement of a pendulum for 20 seconds. When he began, the pendulum was at its resting position. It then moved right (positive displacement) and left (negative displacement) several times. The time it took to move to both sides and then return to its resting position was 4 seconds. The pendulum's farthest position to either side was 8 cm. Graph the pendulum's displacement as a function of time. Allow the x-axis to be measured in seconds and the y- axis to be measured in cm.
