Archimedes' Principle on a Body in Water
Hi. Can someone please walk me through how to do the following problem?
A person with a mass of 81 kg and a volume of 0.089 m^3 floats quietly in water.
(a) What is the volume of the person that is above water?
(b) If an upward force F is applied to the person, the volume above water increases by 0.0018 m^3. Find the force F.

Solution Summary
The solution attaches a document containing very clear thorough explanation of how to do each problem of this question on the Archimedes' Principlem of upward force acting on a buoyant person in water.
Archimedes' Principle, Euler's Equations & Hydrostatic Pressure
Recall the standard vector identity: {see attachment}.
? A body is immersed in water at rest, under gravity. Show from Euler's equations that the pressure is: {see attachment}
(Hydrostatic pressure)
? Deduce that the buoyancy force on the body is equal to the weight of water displaced by it.
? A boat floats on a pond. A crew member carefully lowers a wooden oar into the pond. What happens to the water level in the pond? What about the waterline of the boat?
? The crew member now gently drops the anchor from the boat into the pond. What happens to the water levels now?
