Answer: 20 meters
Explanation:
This situation is related to vertical motion, especifically an object in free fall, and the parametric equation that describes this motion is:
Where:
is the stone's final height
is the stone's initial height
is the initial speed of the stone
is the time the stone is falling
is the acceleration due gravity
Isolating according to the given information:
Finally:
This is the distance the stone fell
