Physics - Wave on String Question with Solution | TestHub

A wave pulse in a string is photographed at $\mathrm{t}=0$. The shape of the string is given by $\mathrm{y}={\mathrm{Ae}}^{-{\mathrm{x}}^2}$. The string is known to have a tension T and mass per unit length of $\mu$. The wave travels in positive x direction. Take ${\int }_0^{\infty }{\mathrm{x}}^2{\mathrm{e}}^{-{\mathrm{x}}^2}\mathrm{dx}=\sqrt{\frac{\pi }{4}},\sqrt{\frac{\mathrm{T}}{\mu }}=4\mathrm{m}/\mathrm{s}$.
