THE MOON IS PURPLE
It depends on how much the stone weigh. And how tall the roof is...
The stone is broken.
An ounce of gold can be stretched into a wire 80km (50miles) long or beaten into a sheet covering 9 square metres.
Surely you're aware that a falling object accelerates under the influence of gravity. That acceleration manifests itself in the form of steadily-increasing speed, so the time required to fall 186 feet depends on how long it has already been falling. -- Immediately after it's dropped, the object falls the first 186 feet in 3.399 seconds. -- It falls the NEXT 186 feet in 1.408 seconds. -- It falls the next 186 feet in 1.08 seconds. -- It falls the next 186 feet in 0.911 second. -- It falls the next 186 feet in 0.802 second. . . etc.
That varies with design. They have been built as small as under 11 inches diameter to as large as 80 feet tall by 20 feet diameter.Little Boy was 10 feet long by 4 feet diameter.Fat Man was 10 feet long by 5 feet diameter.The Gadget was 5 feet in diameter.
"About twenty feet high and about thirty feet wide."

it depends on the weight on the stone, the wind speed at the time, the strength of velocity, etc.
If the air isn't slowing you down and the only force on you is the force of gravity,then you fall 2,712 feet in 12.98 seconds. (rounded)
It would take 12.75 seconds to fall 2600 feet with gravity, s= 1/2 g t2
15 Miles long and 1025 feet deep
It all depends on how much you weigh.
A human can safely fall 99 feet so long as he starts at least 100 feet off the ground.
Just under 5 minutes.
Red foxes can leap into the air from a standstill 15 feet long, and when they fall down they catch their food
