A spring is resting vertically on a table. A small box is dropped onto the top of the spring and compresses it. Suppose the spring has a spring constant of 450 N/m and the box has a mass of 1.5 kg. The speed of the box just before it makes contact with the spring is 0.49 m/s.

(a) Determine the magnitude of the spring's displacement at an instant when the acceleration of the box is zero.

(b) What is the magnitude of the spring's displacement when the spring is fully compressed?
