<h3>
Therefore 45.87 m from which the object was dropped.</h3>
Step-by-step explanation:
Given , the velocity of free fall object is given by
where v is the velocity (m/s) g is acceleration due to gravity (m/s²) and h is the the distance (m) fallen.
v = 30 m/s
g = 9.81 m/s²

⇔v² = 2gh [ squaring both sides]



Therefore 45.87 m from which the object was dropped.

A(x + b) = c
x+b = c / A
x = c/A - b
Hope this helps!
