Question

A transverse sinusoidal wave on a string has a period *T*
= 21.0 ms and travels in the negative *x* direction with a
speed of 30.0 m/s. At *t* = 0, a particle on the string at
*x* = 0 has a transverse position of 2.00 cm and is
traveling downward with a speed of 2.50 m/s.

(a) What is the amplitude of the wave?

0.0217

Your response differs from the correct answer by more than 10%.
Double check your calculations. m

(b) What is the phase constant?

1.97

(c) What is the maximum transverse speed of the string?

6.48 m/s

(d) Write the wave function for the wave. (Use the form
*A*sin(*kx* + *?**t* + *?*).
Round all coefficients to three significant figures.)

*y*(*x*, *t*) =
