I have these two fluids problems and I can't get either one (they are related). Can anyone point me in the right direction?
1. A 3.05 kg piece of wood (SG = 0.500)) floats on water. What minimum mass of copper, hung from it by a string, will cause it to sink?
2. A 3.25 kg piece of wood (SG = 0.500)) floats on water. What minimum mass of lead, hung from it by a string, will cause it to sink completely under water?
Edit: I'm pretty sure the densities of copper and lead are necessary.
copper = 8900 kg/m^3
lead = 11300 kg/m^3
water = 1000 kg/m^3
