A golf club head is made from aluminum having a specific weight of 0.100 lb/in3. In air it weighs 0.500 lb. What would be its apparent weight when suspended in cool water?
Wetsuits are prohibited in some triathlons due to the added buoyancy they provide the swimmer, essentially holding a greater portion of the body above the water and decreasing the power required to swim. If a given suit is made of 1.8 square yards of the material, and it is 0.25 in thick and has a specific weight of 38 lb/ft3, what net buoy-ant effect would aid the swimmer in seawater?
