16.3 Exercise 21

A sinusoidal wave travels down a taut, horizontal string with a linear mass density of $\mu = 0.060 \text{kg}/\text{m}$. The maximum vertical speed of the wave is $v_{y \text{max}} = 0.30 \text{cm}/\text{s} .$ The wave is modeled with the wave equation $y \left(x , t\right) = A \text{sin} \left(6.00 \text{m}^{−1} x - 24.00 \text{s}^{−1} t\right) .$ (a) What is the amplitude of the wave? (b) What is the tension in the string?
