Halliday, Resnick & Walker — Waves–I: Problem Problem_68

A single pulse, given by \( h(x - 5.0t) \), is shown in Fig. 16.22 for \( t = 0 \). The scale of the vertical axis is set by \( h_s = 2 \). Here \( x \) is in centimeters and \( t \) is in seconds. What are the (a) speed and (b) direction of travel of the pulse? (c) Plot \( h(x - 5t) \) as a function of \( x \) for \( t = 2 \text{ s} \). (d) Plot \( h(x - 5t) \) as a function of \( t \) for \( x = 10 \text{ cm} \).
