Floating on Ice: Calculating Volume Needed to Stay Afloat

[TSny]

That's the force of gravity on the person alone. How would you express the total force of gravity on the system? The system consists of the man and the ice.

The total force of gravity is equal to the weight of the person plus the weight of the ice. Post #35 has the weight of the person. Post #31 has the weight of ice. Adding these together gives you the left side of F(g) = F(a). The right side of the equation is the buoyant force given in post #20.
