(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

When mass M is tied to the bottom of a long, thin wire suspended from the ceiling, the wire's second-harmonic frequency is 200 Hz. Adding an additional 1kg to the hanging mass increases the second-harmonic frequency to 245 Hz. What is M?

f[tex]_{2}[/tex] = 200hz, m = M

f[tex]_{2}[/tex] = 245hz, m = M+1

g = 9.8m/s

2. Relevant equations

f=v/L, v = [tex]\sqrt{T/u}[/tex]

3. The attempt at a solution

not sure where to start the problem

please help!

any help is greatly appreciated!
