-- At the beginning of the time, the falling speed of the stone is zero.-- After 3.30 sec, its falling speed is 32.34 meters per second (Acceleration of gravity.)-- Its average falling speed is 1/2(0 + 32.34) = 16.17 meters per second.-- The distance it falls is (average speed) x (time) = (16.17) x (3.30) = 53.361 meters = 175.2 feet(These same steps lead to the formula H = 1/2 G T2 = (0.5) (9.8) (3.3)2 = 53.361)
Let Vo = initial velocity = 0 (m/s) x = vertical displacement t = time and a = gravitational constant = 9.8 meters per second squared (m/s2) x= initial velocity * time + 1/2 acceleration * time squared = Vot + (1/2)at2 = (0*3.1) + (1/2)(9.8)(3.1)(3.1) = 47.089 meters (metric) = 154.5 feet (English conversion)
The sound moves in a second 340 metres. That is in 3.8 seconds 1292 metres. But because there is the way down to the ocean and back to the ears of the stone dropper, the distance must be half of it. The cliff is 646 metres high.
depends on the mass of the stone, the shape of the stone, and the height dropped from. sorry dude.

The spike or droplet of water that rises above the surface when a stone is dropped into water is called a "crown splash" or "crown". It occurs due to the displacement of water caused by the sudden impact of the stone.
The velocity of the stone dropped from a height of 318 meters can be calculated using the formula v = √(2gh), where g is the acceleration due to gravity (9.81 m/s^2) and h is the height (318 m). Substituting the values, the velocity of the stone would be approximately 78.74 m/s.

"Dropped like a stone" is a simile because it uses "like" to compare the action of dropping to a stone.
Stone Mountain, Georgia's elevation doesn't even equal half a mile. It is 1,043 feet (318 meters) above sea level
Let Vo = initial velocity = 0 (m/s) x = vertical displacement t = time and a = gravitational constant = 9.8 meters per second squared (m/s2) x= initial velocity * time + 1/2 acceleration * time squared = Vot + (1/2)at2 = (0*3.1) + (1/2)(9.8)(3.1)(3.1) = 47.089 meters (metric) = 154.5 feet (English conversion)

The building is h=.5 gt^2 meters tall; that is = .5x9.8 x25 =122.5 meters.

The acceleration of the stone when it is dropped from the top of a tower is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 downward. This acceleration remains constant as the stone falls towards the ground, neglecting air resistance.
