Two ships are 335 m aparts from each other are shooting cannons at each other. Both ships' cannons are 3.0 m above the water line and both have a muzzle velocity (speed of the cannon ball) of 217 m/s. The ship on the left fires its cannons horizontally. The ship on the right fires at 15 degrees above the horizontal. Ignore air resistance. Will the cannon ball from the ship on the right reach its maximum height (peak hight) before hitting the ship on the left? Show reasoning and calculations.
