Answer:
48.26 m
Explanation:
time to goes up (till stop for a while in the air - maximum height)
vt = vo + a t
0 = 15 + g . t
0 = 15 + (-9.8) . t
9.8t = 15
t = 1.531 s
so the time left to goes down is
4.0 - 1.531 = 2.469 s
height from the top of building can find it by using
vo =√(2gh)
15 = √(2)(9.8).h
15² = 19.6h
h = 225/19.6 = 11.48 m
so the distance of maximum height to the ground is
t = √(2H/g)
2.469 = √(2H/9.8)
2.469² = 2H/9.8
6.096 = 2H/9.8
2H = 6.096 x 9.8 = 59.74 m
so the vertical distance of the building (or the building height's is)
H - h = 59.74 - 11.48 = 48.26 m
The time of motion of the ball before coming to rest is determined as 5.5 s.
<h3>
Time of motion of the ball</h3>
The time of motion of the ball before coming to rest is calculated as follows;
v = u + at
when the ball comes to rest, v = 0
0 = u + at
0 = 55 + (-10)t
0 = 55 - 10t
10t = 55
t = 5.5s
Thus, the time of motion of the ball before coming to rest is 5.5 s.
