Problem 14.71 DroppingAnchor. An iron anchor with mass 35.5 kg and density 7860 kg/m^3 lies on the deck of a small barge that has vertical sides and floats in a freshwater river. The area of the bottom of the barge is 7.80 m^2. The anchor is thrown overboard but is suspended above the bottom of the river by a rope; the mass and volume of the rope are small enough to ignore. Part A After the anchor is overboard and...
