A sinusoidal wave is sent along a string with a linear density of 5.0 g/m. As it travels, the kinetic energies of the mass elements along the string vary Figure 10-49a gives the rate dk/dt at which kinetic energy passes through the string elements at a particular instant, plotted as a function of distance x along the string. Figure 1649b is similar except that it gives the rate at which kinetic energy passes through a particular mass element at a particular location) plotted as a function of time. For botle figures the scale in the vertical (rate) axis is set by R_s=10W. What is the amplitude of the wave? |
