The general problem -solving approach: Step 1: Draw a force diagram of the solid object, identify all the forces acting on the object and their directions. Step 2: Apply Newton's Laws to write an equation relating the magnitudes of the forces in step 1. Step 3: Apply the formula of the buoyant force (Archimedes principle). Pay attention to what density and what volume are relevant to the buoyant force. Also you may need to write the mass of the solid object in terms of its density and volume. Pay attention to what density and what volume are relevant to the object's mass. Step 4: Solve the obtained equation for unknown quantity (quantites). Part A - A block of ice ( ice = 917 kg/m3) floats in fresh water ( = 1000 kg/m3). Find Vunder/ViceBlock in percentage. (the percentage of Vunder relative to the ice block's entire volume)
