The string shown in the figure (picture is not uploading) is driven at a frequency of 5.00 Hz. The amplitude of the motion is A = 10.0 cm, and the wave speed is v = 21.5 m/s. Furthermore, the wave is such that y = 0 at x = 0 and t = 0.

(a) Determine the angular frequency for this wave. = 31.4 rad/s (CORRECT)

(b) Determine the wave number for this wave. = 1.46 rad/m (CORRECT)

(c) Write an expression for the wave function. (Use the following as necessary: t, x. Let x be in meters and t be in seconds.)
y = _____ sin(1.46x?31.4t)

(d) Calculate the maximum transverse speed.

(e) Calculate the maximum transverse acceleration of an element of the string.
