You are fishing in the local quarry when your friend capsizes the boat while trying to catch a fish. A 45-N bronze fishing trophy, your favorite 225-N maple Captain’s chair, a 230-N block of ice that was to be used to cool the fish, and a 180-N steel bar used to stun the fish are now all in the lake. What is the buoyant force exerted on each of the objects? (The densities are as follows: lake water, 9,807 N/m3; bronze, 858,300 N/m3; maple, 6,300 N/m3; ice, 9,040 N/m3; and steel, 76,500 N/m3.)
