A sinusoidal transverse wave is traveling along a string in the negative direction of an x axis. The figure below shows a plot of the displacement as a function of position at time t= 0. The x axis is marked in increments of 10 cm and the y axis is marked in increments of 2.5 cm. The string tension is 3.1 N, and its linear density is 32 g/m.

(a) Find the amplitude.

(b) Find the wavelength.

(c) Find the wave speed.

(d) Find the period of the wave.

(e) Find the maximum speed of a particle in the string.

(f) Complete the equation describing the traveling wave, in which x and y are in meters, angle in radians, and tis in seconds.
