Problem 3. A block (m = 20 kg, V = 0.15 m³) is attached to a spring with restoring constant k = 2000 N/m. The system is submerged underwater (Pwater = 1000 kg/m³), as shown below. The system is in static equilibrium. P = 1000 kg/m³ water m Part (a) Is the spring stretched or compressed? Defend your reasoning. Part (b) Determine the distance that the mass stretches or compresses the spring. Hint: Start with a free body diagram and set up Newton's 2nd Law. Part (c) Suppose the mass is pushed down 5 cm, displacing it from its equilibrium position found in part (b). Describe the resulting motion of the mass as accurately as possible.
