A block of wood floats on water. The density of the
wood is .634g/cm^3. Its mass is 243 g. Find the minimum mass (g) of lead we
must attach to the block so that it will sink, along with the lead. The density of lead is
11.3 g/cm^3. Caution: you must take into account the buoyant force on the lead, as well
as on the wood.
B=pgV=Mg(weight of fluid displaced)
The Attempt at a Solution
I know that I must apply bouyancy principles to Newton's Second Law but I am not sure exactly how to set up my equations. How should I attack this problem?
