1. The problem statement, all variables and given/known data

A sinusoidal transverse wave is traveling along a string in the negative direction of an x-axis. The figure shows a plot of the displacement as a function of position at time t=0; the y-intercept is 4.0m. The string tension is 6.8N, and its linear density is 47.22 g/m.

Find the amplitude (cm).

Find the wavelength (cm).

Find the wave speed (cm/s).

Find the period of the wave.

Find the maximum transverse speed of a particle in the string.

What is the phase angle in degrees?

2. Relevant equations

3. The attempt at a solution

So linear density is the mass per unit length. it's not in the units we want (kg/cm), so convert and get 4.722E-4 kg/cm.

wave speed = sqrt(T/wave length) = sqrt(6.8/4.722E-4), but this isn't the right answer. did i convert wrong?

also i'm having trouble finding the amplitude and wave length, probably for the same reason as above.
