An expectant father paces back and forth, producing the position-versus-time graph shown in Figure 2-25. Without performing a calculation, indicate whether the father’s velocity is positive, negative, or zero on each of the following segments of the graph: (a)A, (b) B, (c) C, and (d) D. Calculate the numerical value of the father’s velocity for the segments (e) A, (f) B, (g) C, and (h) D, and show that your results verify your answers to parts (a)-(d).
