Question: A (30-mathrm{kg}) block is suspended from a spring with a stiffness of (300 mathrm{~N} / mathrm{m}) and attached to a dashpot of damping coefficient of

A $30-\mathrm{kg}$ block is suspended from a spring with a stiffness of $300 \mathrm{~N} / \mathrm{m}$ and attached to a dashpot of damping coefficient of $120 \mathrm{~N} \cdot \mathrm{s} / \mathrm{m}$. The block is subject to a harmonic excitation of amplitude $1150 \mathrm{~N}$ at a frequency of $20 \mathrm{~Hz}$. What is the block's steady-state amplitude?
