# Homework Help: Wave Power

>> A taut rope has a mass of 0.165 kg and a length of 3.75 m. What power must be supplied to the rope to generate sinusoidal waves having an amplitude of 0.120 m and a wavelength of 0.480 m, traveling with a speed of 30.5 m/s?

I'm not really sure how to start this. I have an equation of power being P=1/2(w^2)(A^2)uv and I have all the information except for w though... is this the right approach? And if it is... how do I find w?

If you know the wavelength and the speed then you can find the frequency:

$$\omega = 2 \pi \frac {v}{\lambda}$$
