Is the speed uniform or nonuniform of a stone dropped from a height?
The speed of a dropped stone will be non-uniform. The stone goes faster as it falls by an amount equal to 32 feet per second, per second. That means for each second of falling, the speed increases by another 32 feet per second until terminal velocity is reached.
What will happen to a stone dropped from the roof of a single story building to the surface of the earth?
The stone would fall straight down from the release point, it would fall with steadily increasing speed, and when it hit the ground, it would stop falling. The rate at which its speed increased during the fall would be 32.2 feet per second faster every second.
How do you answer this physics question?
A ball is thrown vertically upward with an initial speed of 20m/s. Two second later, a stone is thrown vertically (from the same initial height as the ball) with an initial speed of 24m/s. At what height above the release point will the ball and stone pass each other?
How many times faster is the speed of light in a vacuum than the speed of sound air?
100% - sound is vibration of atoms/molecules - it cannot travel through vacuum ___________________________ The idea of "speed pf sound in a vacuum" is meaningless; sound cannot travel without a medium such as air, water, metal, stone, or SOMETHING. Sound waves are mechanical vibrations; there has to be something to vibrate. The speed of sound in air is around 700 miles per hour, while the speed of light is 186,000 miles per SECOND.
Why does angular speeds stay the same even though the linear speeds are different?
because god said it shouild Think of a stone on a string whirling around, two complete turns per second. Suppose the angle that any part of the string, or stone, rotates through is 2x360 degrees per second (=angular spesd). But the stone might be going at 10 feet per second (=linear speed), at the same time that the bit of string 2 inches from your hand is going less than 1 foot per second (linear speed), while the angular speed is still 720 degrees per second. Angular speeds and linear speeds do not even have the same Dimensions: 1/T vs L/T. The question ought to be "why should anyone think these things to be the same?"

A falling stone travel the same speed each second it falls?
A falling stone will increase in speed until it reaches it's terminal velocity, the speed when the downward force of gravity equals the upward force of drag, which causes the net force on the stone to equal zero, thus achieving an acceleration of zero. If atmosphere is ignored, a falling body will accelerate at 32ft/s (9.75m/s). The distance traveled in the first second would be 16 feet (4.87m), in the second second: 48 feet (14.63m) and in the third second: 80 feet (24.38m); hence after three seconds an object would have fallen 144 feet (43.89 meters) and is traveling at 96ft/s (29.26m/s).
When is meant by accleration due to gravity?
Dropping a stone from a tall building is an example of acceleration due to gravity. The stone's speed will increase as it falls until it reaches terminal velocity.
How did the incas use stone to increase farm production?
The Incas used stone to build terraces, known as "andenes," on the steep slopes of mountains to create flat areas for farming. These terraces prevented erosion, helped retain water, and provided microclimates for crops to thrive in different altitudes. The use of stone also allowed for better irrigation systems, such as canals and aqueducts, to bring water to the crops.
A stone was dropped off a cliff and hit the ground with a speed of 96 ft per second what is the height of the cliff?
240 ft
Does a falling stone travel te same distance each second it falls?
No. Since the speed of a falling object keeps increasing, it falls through more distance in each second than it did in the second before.
Does the speed of the stone change during the falling into a river?

Where is the second stone on panfu on the love quest?
The second stone is in the left door of the jungle cave.

It takes 6 s for a stone to fall to the bottom of a mine shaft. How deep is the shaft?
Ignoring air resistance, or bouncing off the sides of the shaft on the way down ...-- Speed when you let it go = 0-- Speed after 6 seconds = 6 G = 58.84 meters per second-- Average speed = 1/2 (0 + 58.84) = 29.42 meters per second-- In 6 seconds, at an average speed of 29.42 meters per second,it fell 176.5 meters.
