Question

A playground is on the flat roof of a city school, 5.6 m above the street below (see figure). The vertical wall of the building is h = 7.10 m high, to form a 1.5-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 2.20 s to reach a point vertically above the wall. PLEASE ANSWER PART C, THANK YOU SO MUCH IN ADVANCE!!!!

Explanation / Answer

Solution-

vy= 18.13sin(53)= 14.48m/s

(c) h=vyt+1/2gt^2
5.6= 14.48t-4.9t^2

4.9t^2-14.48t+5.6=0

t= 2.58s
d=vxt-24

= 18.13cos(53)*2.58-24

= 4.15 m
