Homework Statement
A block of wood has a mass of 3.84 kg and a density of 598 kg/m3. It is to be loaded with lead so that it will float in water with 0.89 of its volume immersed. The density of lead is 1.13 104 kg/m3.
a)What mass of lead is needed if the lead is on top of the wood?
b)What mass of lead is needed if the lead is attached below the wood?
Homework Equations
Fb=MG
mg=.89Fb
The Attempt at a Solution
I don't really know where to begin, .89Fb=mg. but I am confused on how to use density of the wood or the lead to help solve the equation? Any ideas on how to start off the problem?
