While on a vacation in Kenya, you visit the port city of Mombassa on the Indian Ocean. On the coast is an old Portuguese fort with large stone walls rising vertically from the shore. An inscription on a plaque states that the walls are an impressive 44 m high. You find the fort's cannons mounted so that they fire horizontally out of openings near the top of the walls facing the ocean. Calculate the muzzle velocity necessary to hit a ship 300.0 meters from the base of the fort.​
