63. Construct the displacement graph for the subway shuttle train as shown in Figure 2.30(a). Your graph should show the position of the train, in kilometers, from t = 0 to 20 s. You will need to use the information on acceleration and velocity given in the examples for this figure.
64. (a) Take the slope of the curve in Figure 2.76 to find the jogger's velocity at . (b) Repeat at 7.5 s. These values must be consistent with the graph in Figure 2.77.
