A playground is on the flat roof of a city school, h 5.40 m above the street below (see figure). The vertical wall of the building is h -6.80 m high, to form a 1.4-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 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. 18.1 m/s (b) Find the vertical distance by which the ball clears the wall. m (c) Find the horizontal distance from the wall to the point on the roof where the ball lands. m

Children playing in a playground on the flat roof of a city school lose their ball to the parking lot below. One of the teachers kicks the ball back up to the children as shown in the figure below. The playground is 5.60 m above the parking lot, and the school building's vertical wall is h = 6.90 m high, forming a 1.30 m Ngh railing around the playground. The ball is launched 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. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Find the speed (in m/s) at which the ball was launched. m/s (b) Find the vertical.distance (in m) by which the ball clears the wall. (c) Find the horizontal distance (in m) from the wall to the point on the roof where the ball lands. (d) What If? If the teacher always launches the ball with the speed found…

A playground is on the flat roof of a city school, h, - 6.30 m above the street below (see figure). The vertical wall of the building is h= 7.50 m high, to form a 1.2-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 e = 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. m/s (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.
