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
A stone falls from a ledge and takes 8 seconds to hit the ground If the stone has an original velocity of 0 meters per second 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
A stone falls from a ledge it takes 16sec?

A stone is thrown horizontally at 8 ms from a cliff 78.4 m high how far from the base of the cliff will the stone strike the ground?
According to the Laws of Physics, Horizontal Velocity is unaffected by Vertical Velocity. Thus you need to first find how long it will take the stone to hit the ground. Assume: Acceleration due to gravity = 9.8 m/s^2 Velocity due to gravity = 9.8x m/s, where x is seconds Displacement due to gravity = 9.8x^2 m, where x is seconds Set Displacement = to 78.4m 78.4m = 9.8x^2 m and solve for.. x = sqrt(8) = 2 sqrt(2) Then to find displacement horizontally, multiply time*velocity horizontally distance from base of cliff = (2 sqrt(2))s * 8 m/s = 16 sqrt(2) m
A stone falls from rest how fast is it falling after 10 seconds?
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
A stone falls freely from rest. What is its velocity after 8 seconds?
78.4 m/s
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 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
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 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

When a stone is thrown upward at an angle what happens to the vertical component of its velocity as it rises and as it falls?
As the stone rises, the vertical component of its velocity decreases due to the acceleration of gravity acting in the opposite direction of the initial velocity. When the stone falls, the vertical component of its velocity increases in the negative direction as gravity accelerates it downwards.
A stone falls from a ledge and takes 16 seconds to hit the ground the stone has an original velocity of 0 ms how tall is the ledge?
The approximate gravitational acceleration on Earth is 9.8 meters per second. Neglecting air friction is s equals 4.9 times 16 squared. S is equal to 1254.4 meters which is equal to 4100 feet.
