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 Asin(kx + ?t + ?). Round all coefficients to three significant figures.)
y(x, t) =
