Answer
$k=8300N/m$
Work Step by Step
In the explanation, it can be concluded that the two forces present equal out. These are the spring force ($kx$) and the weight ($mg$). This means that $$mg=k\Delta x$$ Solving for $k$ yields $$k=\frac{mg}{\Delta x}$$ Substituting known values of $m=110. kg$, $\Delta x=13cm=0.13m$, and $g=9.80m/s^2$ yields a force constant of $$k=\frac{(110.kg)(9.80m/s^2)}{0.13m}=8300N/m$$
