The U. S.S. Constitution, the oldest fully commissioned war ship in the world,
is docked in Boston, Massachusetts. Also known as âOld Ironsidesâ for her
seemingly impenetrable hull, the frigate houses 56 pieces of heavy artillery.
Mounted on bearings that allow them to recoil at a speed of 1.30 m/s are
20 carronades, each with a mass of 1000. kg. If a carronade fires a 14.5-kg
cannonball straight ahead, with what muzzle velocity does the cannonball
leave the cannon?
