The figure below shows a plot of displacement as a function of position at time t=0. It represents a
sinusoidal transverse wave formed in a string traveling in the direction of decreasing x. The tension in
the string is 3.64 N and its mass per unit length is 28.7 g/m.
The amplitude is 4.2 cm. Calculate the wave speed.
Answer:
1.13e+01 m/s
