## Homework Statement

http://img683.imageshack.us/i/wave2.jpg/The above figure shows height vs. displacement plot for a string which has a wave traveling to in the positive x direction at time t=2.5 sec with a velocity of 38 m/sec. What is the vertical (y) velocity of a piece of string at the point labeled 1?

vy= _____ cm/sec

## Homework Equations

## The Attempt at a Solution

The horizontal velocity at point 1 is zero so I figured the given velocity is the vertical velocity.

38 (m/s) * (100 cm/ 1 m) = 3800 cm/s but this is incorrect and I am out of ideas.
