Problem

2\,\text{kg}

wooden block of density

500\,\text{kg/m}^{3}

is submerged in water and held in place by a vertical spring attached to the bottom. The spring constant is

k = 100\,\text{N/m}

. Determine the extension in the spring at equilibrium. (Take

g = 10\,\text{m/s}^{2}

, water density

= 1000\,\text{kg/m}^{3}
