Q: A sinusoidal wave of the form: [tex]y = A \sin{kx - \omega t}[/tex] is traveling along a string in the x direction, where A = 0.88 mm, k = 2 m^-1, omega = 25 rad/s, with x in meters and t in seconds. For this string, the mass per unit length is given by mu = 0.01 kg/m.(adsbygoogle = window.adsbygoogle || []).push({});

For a length segment delta x = 1 cm along the string, what is the total energy of oscillation? Answer in units of J.

Comments:

First I tried [tex]E_\lambda = U_\lambda + K_\lambda = \frac{1}{2} \mu \omega^2 A^2 \lambda[/tex] but that was wrong so then I changed the lamda to delta x, and that was wrong as well. How do we compute the total energy of a small line segment? thanks.
