The cannon on a pirate ships shoots cannon balls with a speed of 350 m/s (the muzzle velocity). The cannon can be adjusted to shoot at any elevation above the horizontal. What is the greatest kinetic energy the cannon ball can have when it hits its target in J? Ignore air resistance and assume the target is at the same height above the ground (or water) as the cannon. When the cannon ball is shot, what impulse is delivered to the ship in (answer with a positive number)?
