## Homework Statement

The tension in the string is 90N; the string is 60cm long and has a weight of 34.44g. What is the speed of the wave on the string?

Answer: 396 m/s

## Homework Equations

v = √ T / (m/L)

## The Attempt at a Solution

v = √ 90N / (0.0344kg/0.6m)

v = 39.6 m/s

Huh? This looks like it should be pretty simple, plug in and get the answers...

What am I doing wrong, i need one more digit!??
