An ice sheet with area 10:0 m x 10:0 m and uniform thickness of 1.20 m floats in the Arctic Ocean. Assume that the density of ice is 917 kg/m3 and the density of seawater is 1030 kg/m3.
(a) Find the buoyant force acting on the ice sheet.
(b) By how much does the ice sheet stick above the surface of the water if a polar bear with mass 520 kg climbs on top of it.
