A spring is attached to the bottom of an empty swimming pool, with the axis of the spring oriented vertically. An 7.55-kg block of wood (density = 715 kg/m3) is fixed to the top of the spring and compresses it. Then the pool is filled with water, completely covering the block. The spring is now observed to be stretched twice as much as it had been compressed. Determine the percentage of the block's total volume that is hollow. Ignore any air in the hollow space.

A spring oriented vertically is attached to a hard horizontal surface as in the figure below. The spring has a force constant of 1.32 kN/m. How much is the spring compressed when a object of mass m = 3.00 kg is placed on top of the spring and the system is at rest? The bottom end of a vertical spring is attached to a horizontal surface, and the top end is attached to a horizontal platform, which supports a block...

A light spring of constant 177 N/m rests vertically on the bottom of a large beaker of water. A 4.42 kg block of wood of density 669 kg/m3 is connected to the top of the spring and the block-spring system is allowed to come to static equilibrium. What is the elongation ∆L of the spring? The acceleration of gravity is 9.8 m/s 2 . Answer in units of cm.

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
