(a) 18.13
(c) 2.19
I only need the answer for part b. I tried to solve it, but when I submit the answer it says that it is incorrect. Please, help! Thank you.
A playground is on the flat roof of a city school, hb = 6.50 m above the street below (see figure). The vertical wall of the building is h = 8.00 m high, to form a 15-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 = 53.0° above the horizontal at a point d-24.0 m from the base of the building wall. The ball takes 220 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 wal (c) Find the horizontal distance from the wall to the point on the roof where the ball lands.Explanation / Answer
Solution: - tan 53 = h/24
h = 24 tan 53
h = 24 X 1.327=31.85 m
