68 A single pulse, given by h(x – 5.01), is shown in Fig. 16-45 for t = 0. The scale of the vertical axis is set by h. = 2. Here x is in centimeters and t is in seconds. What are the (a) speed and (b) di- rection of travel of the pulse? (c) Plot h(x - 5t) as a function of x for t = 2 s. (d) Plot h(x tion of t for x = 10 cm. 5. 5t) as a func- Figure 16-45 Problem 68. 68 A single pulse, given by h(x – 5.01), is shown in Fig. 16-45 for t = 0.
