(a) Using a metric ruler, measure the position of the center of my body from the left edge in each frame of Figure 2.1. Compare your list of values with the positions given in Table 2.1.

(b) Plot the positions you measured as a function of frame number-no need for graph paper, just draw your axes and plot your data by eye.

Figure 2.1 Film clip showing me walking to the right, pausing, then walking back to the left. The camera recorded this event at 30 frames per frame number (three frames per second) 1 second; only one frame in ten is reproduced here. Using a ruler, you can determine the position of the center of my body in each frame. For instance, in frame 5, this position is 8.5 mm from the left edge of the frame; in frame 10, it is 12.0 mm from the left edge. walking forward pausing 3 10 10 frame 5 10l millimeters 8.5 mm frame 10 201 10 201 11 millimeters 12.0 mm 12 13 14 15 walking 16 backward 17 18 19
