2. Relevant equations

3. The attempt at a solution

## v = \frac { \omega } k ##

## \omega = \sqrt{ kg \tanh (k) } ##

I have no idea to guess the graph.

I put g = 9.8 and tried to calculate ## \omega ## for different values of k.

## \omega (0 ) = 0,

\omega (30) = 17.15

~~\omega (20) = 14 ##

But, these values don’t match any of the graph.

So, what to do now?
