From what height did the apple fall if, when hitting the ground, it had a speed of 5 m / s?

The height from which the apple fell can be calculated using the formula:
S = (V² – V0²) / 2a,
where V is the final speed of the apple (V = 5 m / s), V0 is the initial speed of movement (the apple fell without initial speed, V0 = 0 m / s), and is the acceleration of the apple (a = g, g is the acceleration of gravity (we take g = 10 m / s²)).
Let’s calculate the height of the fall of the apple:
S = (V² – V0²) / 2a = V² / 2g = 5² / (2 * 10) = 25/20 = 1.25 m.
Answer: The apple fell from a height of 1.25 m.
