16.2 Exercise 9

A transverse wave on a string is modeled with the wave function $y \left(x , t\right) = \left(0.20 \text{cm}\right) \text{sin} \left(2.00 \text{m}^{−1} x - 3.00 \text{s}^{−1} t + \frac{\pi}{16}\right) .$ What is the height of the string with respect to the equilibrium position at a position $x = 4.00 \text{m}$ and a time $t = 10.00 \text{s} ?$
