A playground is on the flat roof of a city school, 4.9 m abovethe street below (see figure). The vertical wall of the building ish = 6.40 m high, to form a 1.5-m-high railing around theplayground. A ball has fallen to the street below, and a passerbyreturns it by launching it at an angle of θ = 53.0° abovethe horizontal at a point d = 24.0 m from the base of thebuilding wall. The ball takes 2.20 s to reach a point verticallyabove the wall.
(c) Find the horizontal distance from the wall to the point onthe roof where the ball lands. (3 sig figs)
