A light spring of force constant k = 160 N/m rests vertically on the bottom of a large beaker of water (see figure (a)). A 5.00-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 (see figure (b)). What is the elongation ΔL of the spring? Include a free-body diagram for the block. (Hint: Begin your derivation with equilibrium: “ΣF = 0”. The derivation is a little complex, so don’t give up, and don’t be tempted to calculate the numerical answer in pieces.)

Question
A light spring of force constant k = 160 N/m rests vertically on the bottom of a
large beaker of water (see figure (a)).
A 5.00-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 (see figure (b)).
What is the elongation ΔL of the spring?
Include a free-body diagram for the block.
(Hint: Begin your derivation with equilibrium: “ΣF = 0”. The derivation is a little complex, so don’t give up, and don’t be tempted to calculate the numerical answer in pieces.)
