The density of ice is 917 kg/m3, and the density of sea water is 1025 kg/m3. A swimming polar bear climbs onto a piece of floating ice that has a volume of 6.83 m3. What is the weight of the heaviest bear that the ice can support without sinking completely beneath the water?

Answer #1

Density of ice = 917 kg/m^3
Volume of ice = 6.83 m^3
Mass of ice = Volume x Density = 917 x 6.83 = 6263.11 kg
Weight of ice = 6263.11 x g = 61378.478 N
Density of sea water = 1025 kg/m^3

When the bear is on top, the WHOLE ice will b submerged, meaning the whole volume of the ice is underwater.

Buoyant force = V(d)(g) , where V is the volume of ice, d is the density of the SEA WATER, g is the gravitational acceleration.

Buoyant force = (6.83 )(1025)(9.8) = 68607.35 N

The weight of the bear = Buoyant force - Weight of ice = 7228.872 N

Mass of bear = Weight of bear / 9.8 = 737.64 kg

Chapter 14, Problem 041 What fraction of the volume of an iceberg (density 917 kg/m3) would be visible if the iceberg floats in (a) the ocean (salt water, density 1024 kg/m3) and (b) in a river (fresh water, density 998 kg/m3)? (When salt water freezes to form ice, the salt is excluded. So, an iceberg could provide fresh water to a community.)

The density of water at 0°C is very nearly 1000 kg/m3 (it is actually 999.84 kg/m3), whereas the density of ice at 0°C is 917 kg/m3. The bulk modulus of ice is 2.20 × 109 Pa.    Calculate the pressure, in pascals, necessary to keep freezing water from expanding, neglecting the effect such a large pressure would have on the freezing point. (This problem gives you only an indication of how large the forces associated with freezing water might be.)

The density of gold = 19, 300 kg/m3 which is 19 times the density of water. Can gold float on water? Explain. 2/5 of the volume of a solid is under water of density = 1000 kg/m3; find the density of the solid; (c) the same solid floats so that 3/5 of its volume is under liquid. Find the density of liquid. Volume of the solid = 5.0 x 10-3 m3
