<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.
