a bore of 900. mm and fires a 2.00 ton shell with amuzzle velocity of 200. ft/s that produces a crater 38.0 ft wideand 20.0 ft deep. As chief engineer of Army Ordnance, you areto design a ballistic pendulum for this gun. If the distance fromthe fulcrum of the pendulum to the point of impact is 10.0 ft,how much mass would the pendulum have to contain ifdeflection of its suspension cord is not to exceed 20.0°?
