How long does a stone fall from the leaning tower of Pisa if its height is 55.86 at the bottom?

Problem data: H (height of the Leaning Tower of Pisa, distance covered by the stone) = 55.86 m.

Reference data: g (acceleration due to gravity) = 9.81 m / s2.

The duration of the fall of the stone from the Leaning Tower of Pisa can be expressed from the formula: H = g * t2 / 2, whence t = √ (2H / g).

Let’s perform the calculation: t = √ (2 * 55.86 / 9.81) = 3.37 s.

Answer: The stone will fall from the Leaning Tower of Pisa for 3.37 seconds.
