A stone falls freely from rest. How far does it fall during the first 10 seconds?
490 meters
A stone falls freely from the rest for 8.0s Calculate the stone's velocity after 8.0s. What is the stone's displacement during this time?
Velocity* v = u + at * v = 0 + 9.8 x 8 * v = 78.4 m/sDisplacement* s = ut + ½at2 * s = 0 + ½ x 9.8 x 82 * s = 4.9 x 64 * s = 313.6 m
When will a stone return to the groun if it is thrown upward with an initial velocity of 16ms?
After just over three and a quarter seconds.
Why does paper falls slowly then stone?
Paper falls more slowly then a stone because paper weighs less then stones.
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.

490 meters
A stone falls freely from rest The total distance covered by it in the last second of its motion equals the distance covered by it in the first three seconds How long does the stone remain in air?

A stone falls freely from the rest what is its velocity after 8 seconds?
The acceleration of gravity is 9.8 meters (32.2 ft) per second2.Neglecting air resistance . . .After 8 seconds, the speed is (9.8 x 8) = 78.4 meters per second. (rounded)After 8 seconds, the speed is (32.2 x 8) = 257.6 feet per second. (rounded)

A stone of mass falls freely through a vertical distance it's kinetic energy will be?
mgh or (1/2)mv2
What is the final velocity of a stone with an original velocity of 0 falling from a ledge that takes 8 seconds to hit the ground?
On Earth gravity equals 9.8 m/s^2. If you multiply that by 8 seconds you get: 78.4m/s
When will a stone return to the groun if it is thrown upward with an initial velocity of 16ms?
After just over three and a quarter seconds.
A stone falls from a ledge it takes 16sec?
If a stone falls from a ledge and takes 16 seconds to hit bottom, then the bottom is 1413 meters away. This assumes acceleration due to gravity of 9.81 meters per second squared, an initial velocity of zero, and no friction due to air resistance. Air resistance will decrease the distance.x = 1/2 at2 + v0t + x0
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.
What happens when you tie a stone to a string and whirl it?
When we tie a stone to a string and whirl it, it moves in a circular path.If the velocity becomes too high then the stone changes to a mass of electrons.It starts radiating energy and ultimately falls in our hand.the energy emitted by the stone is given by E = hv.Where h is Plancks constant and v is the radial velocity of the stone.
A stone falls from a ledge and takes 8 seconds to hit the ground the stone has a original velocity of 0 ms how tall is the ledge?
H = 1/2 g T2 = (4.9) (64) = 313.6 meters.H = 1/2g T2 = (4.9) x (8)2 = 4.9 x 64 = 313.6 meters
