You are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 31∘ from the edge of the building with an initial velocity of 21 m/s and lands 63 meters away from the wall. How tall, in meters, is the building that the child is standing on? m

A baseball is thrown from the roof of h = 23.4-m-tall building with an initial velocity of magnitude 11.3 m/s and directed at an angle of 53.1∘ above the horizontal. For related problemsolving tips and strategies, you may want to view a Video Tutor Solution of Energy in projectile motion. Part A What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. Express your answer in meters per second. Part B What is the answer for part (A) if the initial velocity is at an angle of 53.1∘ below the horizontal Express your answer in meters per second. v2 = m/s Submit Request Answer Part C If the effects of air resistance are included, will part (A) or (B) give the higher speed? The part (A) will give the higher speed. The part (B) will give the higher speed.

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 4.70 m above the parking lot, and the school building's vertical wall is h = 6.10 m high, forming a 1.40 m high railing around the playground. The ball is launched at an angle of θ = 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-including answers submitted in WebAssign-in your calculations.) (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. m (c) Find the horizontal distance (in m) from the wall to the point on the roof where the ball lands. m (d) What If? If the teacher always launches the ball with the speed found in part (a), what is the minimum angle (in degrees above the horizontal) at which he can launch the ball and still clear the playground railing? (Hint: You may need to use the trigonometric identity sec2⁡(θ) = 1+tan2⁡(θ).) ∘ above the horizontal (e) What would be the horizontal distance (in m) from the wall to the point on the roof where the ball lands in this case? m
