Homework Statement
A polar bear of mass 520 kg is floating on an iceberg in the ocean. As the ice melts, how small can the iceberg get before the bear gets wet feet? (The answer should be the volume of the iceberg).
Homework Equations
Buoyant Force, Fb = p(fluid)V g
From a table in my textbook, p(ice)= 920 kg/m^3 and p(sea water)= 1030 kg/m^3
The Attempt at a Solution
I did a sum of the forces in the y-direction to be zero and obtained:
Fb - W(bear) - W(ice)= 0
p(sea water)V = 520 + p(ice)V
V= 4.73 m^3
My answer is wrong... PLease help...
