A playground is on the flat roof of a city school, 6.00m above the street below. The vertical wall of the building is h=7.00m high, forming a 1-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle ofɵ=53.0oabove the horizontal at a point d=24.0 m from the base of the building wall. The ball takes 2.20s to reach a point vertically above the wall. Find the vertical distance by which the ball clears the wall.
