A playground is on the flat roof of a city school, 6.00 m above the street below (Fig. P4.25). The vertical wall of the building is h = 7.00 m high, forming a l-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launch- ing it at an angle of 0 = 53.0° above the horizontal at a point d= 24.0 m from the base of the building wall.

. A playground is on the flat roof of a city school, 6.00 m
above the street below (Fig. P4.25). The vertical wall
of the building is h= 7.00 m high, forming a l-m-high
railing around the playground. A ball has fallen to
the street below, and a passerby returns it by launch-
ing it at an angle of 0 = 53.0° above the horizontal at a
point d = 24.0 m from the base of the building wall. The
ball takes 2.20 s to reach a point vertically above the
wall. (a) Find the speed at which the ball was launched.
(b) Find the vertical distance by which the ball clears
the wall. (c) Find the horizontal distance from the wall
to the point on the roof where the ball lands.
