Here is your answer ___________.
===============================
Let
h=height of the building
The acceleration due to gravity is
g=9.8ms^−2
The distance travelled by the stone from the top of the building is
=lm
The distance travelled by the stone from the top of the building is
=(h−l)m
Apply the equation of motion,
s=ut+1/2at^2
The time is
t=3s
For the stone thrown from the top of the building
l = 0×3+1/2×9.8×3^2=44.1m
For the stone thrown from the bottom of the building
h−l=20×3−1/2×9.8×3^2=60
−44.1m = 15.9m
Therefore,
the height of the building is
h=15.9 +44.1 = 60m
=============================
Hope it helps you ☺☺☺
