*27 O A sinusoidal wave is sent along a string with a lineardensity of 2.0 g/m. As it travels, the kinetic energies ofthe mass elements along the string vary. Figure 16-37a gives therate dKldt at which kinetic energy passes through the string ele-ments at a particular instant, plotted as a function of distance xalong the string. Figure 16-37b is similar except that it gives therate at which kinetic energy passes through a particular mass ele-ment (at a particular location), plotted as a function of time t. Forboth figures, the scale on the vertical (rate) axis is set by R, = 10 W.What is the amplitude of the wave?R,0.10.2x (m)t (ms)(a)(b)

The wave is a particular type of pulse that can propagate through a large crowd gathered at a sports arena (Fig. P16.4). The elements of the medium are the spectators, with zero position corresponding to their being seated and maximum position corresponding to their standing and raising their arms. When a large fraction of the spectators participates in the wave motion, a somewhat stable pulse shape can develop. The wave speed depends on peoples reaction time, which is typically on the order of 0.1 s. Estimate the order of magnitude, in minutes, of the time interval required for such a pulse to make one circuit around a large sports stadium. State the quantities you measure or estimate and their values.
