Answer :
Final answer:
The height of the building is approximately 3829.6 meters.
Explanation:
To calculate the height of the building, we can use the equation for free fall:
h = (1/2)gt^2
Given that the stone takes 28 seconds to hit the ground, we can substitute this value into the equation:
h = (1/2)(9.8 m/s^2)(28 s)^2
Simplifying the equation:
h = (1/2)(9.8 m/s^2)(784 s^2)
h = 3829.6 m
Therefore, the height of the building is approximately 3829.6 meters.

Explanation:the answer is c 39.2m
The question said to calculate the height of the building but first we must find the velocity in which the stone end with after hit the ground
From eq........ 1
V=u+gt
Where v=final velocity
U=initial velocity
G=gravity
T=time
The question said the stone dropped from rest this mean initial velocity is zero
V=u+gt
V=0+10*28
V=280
So now we have final velocity we can find the height of building
From eq.......... 3
[tex]v {}^{2} = u {}^{2} + 2gh[/tex]
[tex]280 {}^{2} = 0 {}^{2} + 2 \times 10 \times h[/tex]
784=20h
[tex]h = \frac{784}{20} [/tex]
[tex]h = 39.2[/tex]
