27. We note from the graph (and from the fact that we are dealing with a cosine-squared, see Eq. 16-30) that the wave frequency is f = 1 2 ms = 500 Hz, and that the wavelength λ = 0.20 m. We also note from the graph that the maximum value of dK/dt is 10 W. Setting this equal to the maximum value of Eq. 16-29 (where we just set that cosine term equal to

Unformatted text preview: 1) we find 1 2 v 2 y m 2 = 10 with SI units understood. Substituting in = 0.002 kg/m, = 2 f and v = f , we solve for the wave amplitude: y m = 10 2 2 f 3 = 0.0032 m ....
