EXAMPLE $2$

Suppose you knew the mass per unit length of the string, $1\mathrm{.}75$e$-3$k$($g$)/($m$),$ and its total length,

$1\mathrm{.}74$ m $,$ but didn't know the hanging mass. Using the same diagrams as above, you should

know how to find the tension, and the amount of hanging mass $(0\mathrm{.}300$kg$)183\mathrm{.}5($m$)/($s$)(305\mathrm{.}9$Hz$)$

Both examples please!
