The U. S.S. Constitution, the oldest fully commissioned war ship in the world, is docked in Boston, Massachusetts. Also known as "Old Ironsides" 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 1.75 m/s are 20 carronades, each
with a mass of 1100 kg.
a) If a carronade fires a 15 kg cannonball straight ahead, with what muzzle
velocity does the cannonball leave the cannon?

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
