## Homework Statement

A 0.5 kg block of wood is floating in water. What is the magnitude of the buoyant force acting on the block.

## Homework Equations

B=Buoyant force: W=weight; fl=fluid; m=mass; V=volume; DEN=density;

There are a couple of equations that our professor gave us, but I am totally confused how to use them.

B=Wfl & Wfl=Wm & Vm>Vfl & DENflVfl=DENmVm

## The Attempt at a Solution

I have figured weight of the mass--W=mg, which is 4.9N

Looking at the first two equations, I would lean toward the thought that 4.9N is the answer, but that seems too easy. Am I making this more complicated than it needs to be, or I am truly as confused as I feel?
