CHAPTER 7: Work and Energy Question 1 The barrels of the guns on the World War lI battleship U.S.S. Massachusetts were each 15 m long. The shells each had a mass of 1250 kg and were fired with sufficient explosive force to provide them with a muzzle velocity of 750 m/s. Use the work-energy principle to determine the explosive force (assumed to be constant) that was applied to the shell within the barrel of the gun. Assume that the barrel is horizontal when fired -does this make much difference? Start your working out with a fully labelled diagram that contains all the information that you have been given in the question.
