The plank you are going to walk has a length of 9.31 m and a mass of 15.16 kg. The plank is not bolted down but is to be placed so that 2.62 m of the plank are actually in contact with the boat. The rest of the board overhangs the jelly fish infested waters. You have a mass of 77.8 kg. What is the minimum mass you must put on the end of the board that is still on the ship so that you can successfully walk to the end of the plank without have the board rotate you into the water
