A piece of electronic equipment that is surrounded by packing material is dropped so that it hits the ground with a speed of 4 m/s. After contact, the equipment experiences an acceleration of a = –kx, where k is a constant and x is the compression of the packing material. If the packing material experiences a maximum compression of 20 mm, at which point the box comes to a complete stop, determine the maximum acceleration of the equipment.
