Ivenika [448]
<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 v = \sqrt{2gh} 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

v = \sqrt{2gh}

⇔v² = 2gh [ squaring both sides]

\Leftrightarrow h =\frac{v^2}{2g}

\Leftrightarrow  h =\frac{30^2}{2 \times 9.81}

\Leftrightarrow  h = 45.87

Therefore 45.87 m from which the object was dropped.
