Note that the origin of the axes is at the legs of the snowboarder for time t = 0. The plot for the "Legs" has been marked up to t = 0. You need to complete the Legs plot across the screen from point t = 0 onward. To do so, mark the Legs position on every frame by holding down the Shift key and clicking the mouse (crosshair cursor) as the video automatically steps through the video clip. See how to plot points. Hint: Zoom your browser display to at least 125% for this marking step, to get the best accuracy in marking the center of the "marker patch" on each frame. After you've plotted the rest of the points for the legs, return your browser's "zoom" setting to 100%. Now look at the graphs for the horizontal and vertical displacement of the legs against time. How do the two graphs, x vs. t and y vs. t appear? What can you say about the displacement of the snowboarder?
