The barrels of the 16-in guns (bore diameter = 16 in = 41 cm ) on the World War II battleship U.S.S. Massachusetts were each 15 m long. The shells each had a mass of 1350 kg and were fired with sufficient explosive force to provide them with a muzzle velocity of 790 m/s . Use the work-energy principle to determine the explosive force (assumed to be a constant) that was applied to the shell within the barrel of the gun. Express your answer in both (a) newtons and (b) in pounds.
