Kyle throws a ball horizontally from the top of a building that is 5.0 m high. He hopes the ball will reac pool that is at the bottom of the building, 12.0 m horizontally from the edge of the building. If the ball is to reach the
pool, with what initial speed must Kyle throw it with? (Assume that there is no air resistance.)
