A sphere is attached to a vertical spring of constant k = 11,990 N/m. As the sphere is allowed to hang from the spring, it also is partially submerged in water, where 60% of its volume is underwater. When the sphere is in equilibrium, it has displaced the spring by 10.0 cm from its relaxed length. The density of the sphere is 4250 kg/m3. (a) Has the spring stretched or compressed? Explain. (b) What is the radius of the sphere?

A spring with spring constant 32 N/m is attached to the ceiling, and a 4.7-cm-diameter, 1.2 kg metal cylinder is attached to its lower end. The cylinder is held so that the spring is neither stretched nor compressed, then a tank of water is placed underneath with the surface of the water just touching the bottom of the cylinder. When released, the cylinder will oscillate a few times but, damped by the water, quickly reach an equilibrium position. When in...
