# Maximum speed of point on a string (Waves)

jegues

## Homework Statement

Suppose the maximum speed of a strong carrying a sinusoidal wave is $$v_{s}$$. When the displacement of a point on the string is half its maximum, what is the speed of the point?

Express your answer in terms of $$v_{s}$$

## The Attempt at a Solution

Well the speed of the wave and the speed of a point on the wave must be two different things, correct?

How can I relate the two?

Thanks again!

I think vs is the maximum speed of a point on the string.

$$\frac{\sqrt{3}v_{s}}{2}$$
