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

A horizontal, parallel-sided plate of glass having a refractive index of 1.47 is in contact with the surface of water in a tank. A ray coming from above in air makes an angle of incidence of 38.0∘ with the normal to the top surface of the glass. Part A What angle does the ray refracted into the water make with the normal to the surface? Use 1.33 for the index of refraction of water. Express your answer in radians. θ = radians
