A sinusoidal transverse wave is traveling along a string in the negative direction of an x axis. Figure shows a plot of the displacement as a function of position at time t = 0; the scale of the y axis is set by y_s= 4.0 cm. The string tension is 3.6 N, and its linear density is 25 g/m. Find the 

(a) Amplitude, 

(b) Wavelength,

(c) Wave speed, and 

(d) Period of the wave. 

(e) Find the maximum transverse speed of a particle in the string. If the wave is of the form y(x, t) = y_m sin (kx + wt + Φ), what are (f) k,

(g) w, 

(h) Φ, and 

(i) The correct choice of sign in front of w?
