A piece of electronic equipment that is surrounded by packing material is dropped so that it hits the ground with a speed of $4 \mathrm{m} / \mathrm{s}$. After contact the equipment experiences an acceleration of $a=-k x,$ where $k$ is a constant and $x$ is the compression of the packing material. If the packing material experiences a maximum compression of $20 \mathrm{mm}$, determine the maximum acceleration of the equipment.
