Search: 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 1050 kg and were fired with sufficient explosive force to provide them with a muzzle velocity of 730 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
Answered by drwls
(avg. force)*(barrel length) = (kinetic energy at muzzle velocity)

F = (1/2)M V^2/L

The barrel diameter does not enter into the calculation. To convert Newtons to pounds of force, use
1 N = 0.225 lb
