## Homework Statement

A brother and sister try to communicate with a string tied between two tin cans. If the string is 9.5m long, has a mass of 55g and is pulled taut with tension 6N, how much time does it take for a wave to travel from one end of the string to the other?

## Homework Equations

v=√(F/M)

M=mass/length

t=d/v

## The Attempt at a Solution

First, I converted 9.5m to 950cm and 55g to .055kg

I used these to find M=.055/950

M=5.7* 10^-5

I used F=6N and divided that by M, then took the square root and i got

v=321.96

then I divided 950 by 321.96 in order to get the time, and got

t=2.95 but this is incorrect.
