A light spring of constant k = 156 N/m rests vertically on the bottom of a large beaker of water (Fig. P9.34a). A 4.10 kg block of wood (density = 650 kg/m3) is connected to the spring and the block-spring system is allowed to come to static equilibrium (Fig. P9.34b). What is the elongation, ΔL, of the spring?
