Q. A play place is on the flat roof of a city school, 6.00 m above the street below. The vertical wall of the building is 7.00 m high, forming a 1.00 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 of 53.0° above the horizontal at a point 26.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall.

Find speed at which the ball was launched.

Find vertical distance by which the ball clears the wall.

Find distance from the wall to the point on the roof where the ball lands.
