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 basketball hoop is 2.90m above the ground. Lee is 1.96m tall, and the maximum vertical distance between the tip of his hands and the bottom of his feet iS 2.81m. To dunk a basketball, the tip of his hands must be at 0.190m above the basketball hoop or more.
What minimum vertical distance in m must Lee jump so that he dunks a basketball?
