Halliday, Resnick & Walker — Waves-I: Problem 1

1 A stretched string has a mass per unit length of 5.00 g/cm and a tension of 10.0 N. A sinusoidal wave on this string has an amplitude of 0.16 mm and a frequency of 100 Hz and is traveling in the negative direction of an x axis. If the wave equation is of the form \(y(x, t) = y_m \sin(kx \pm \omega t)\), what are (a) \(y_m\), (b) \(k\), (c) \(\omega\), and (d) the correct choice of sign in front of \(\omega\)?
