A flat slab of styrofoam, with a density of 32kg/m^3 , floats on a lake. What minimum volume must the slab have so that a 33kg boy can sit on the slab without it sinking?
A person is swimming 0.91 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.4 m above the water. From what height was the ball actually dropped?
A person is swimming 0.87 m beneath the surface of the water in a swimming pool. A child standing on the diving board drops a ball into the pool directly above the swimmer. The swimmer sees the ball dropped from a height of 5.3 m above the water. Part A From what height was the ball actually dropped?
A hailstone (frozen water) of diameter 7 cm (at melting point temperature) falls into a lake with a water temperature of 25degreeC, and floats in the water 1 m beneath the water surface. What is the heat loss into the hailstone from the surrounding water just after the stone entered it? Assuming the heat loss value remains constant, roughly estimate how long it would take for 30% of the hailstone to melt.

To a person swimming 0.815 m beneath the surface of the water in a swimming pool, the diving board directly overhead appears to be a height of 5.00 m above the swimmer. 1.) What is the actual height of the diving board above the surface of the water?
A Canada goose floats with 24.1% of its volume below water. What is the average density of the goose? kg/m3
A hollow sphere of mass 110 kg is chained to the bottom of a lake such that the sphere floats 30 meters above the bottom of the lake with the chain tight. The total depth of the lake is 122 meters at the location where the sphere is chained. The density of water is 1000kg/m3. The radius of the hollow sphere is 1 meter. 1. The density of rock is approximately 2300kg/m3. If a spherical rock of radius 25 cm...
