Answer:
The final velocity, , is gd.
Explanation:
The condition here is a free falling object. Thus from the third equation of motion under free fall, we have;
= + 2gs
where is the final velocity of the object, is the initial velocity of the object, g is the gravitational force and s is the height.
Since the object falls from a height of d, then = 0 m/s, and s = d.
So that;
= 0 + 2gd
= 2gd
= 2gd
When the distance is , = 0 m/s.
Then;
= 2g
= g x d
When the object falls through the height , then the final velocity is gd.
