(a) Consider my motion between frames 6 and 17 in Figure 2.1. Use the values in Table 2.1 to determine the answers to these questions: What is my average speed over this time interval? What is the \(x\) component of my average velocity? What is the average velocity?

(b) Repeat for the motion between frames 1 and 17.

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) 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
