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.

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
An apple falls from a tree What is its velocity after 1.6 seconds?
The acceleration of gravity is 9.8 meters per second2 downward. 1.6 seconds after falling from a branch near the surface of the Earth, the apple's speed is 15.68 meters per second. It's velocity is 15.68 meters per second downward. The tree has to be really tall, since the apple falls 12.544 meters (about 41 feet) in 1.6 seconds.
A 12 kg rocks falls from rest off a cliff and hits the ground in 1.5 s.without considering air resistance what is the rock s velocity just before it hits the ground?
The velocity is gravity acceleration x time or (9.8)(1.5) = 14.7 m/s. The velocity is not dependent on the mass.
A stone falls from a ledge and takes 8 seconds to hit the ground?
A stone that falls from a ledge and takes 8 second to hit the ground travels a distance of 313.6 meters. You can find this answer by substituting 8 seconds for time in the physics formula d = 1/2 x acceleration x (t squared), where d = distance, acceleration is given as a =9.8 meters/second squared, and t squared is time in seconds.
The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 91 ft in 2 seconds how far will it have fallen?
The answer is 91 ft, of course!
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
the crate will reach terminal velocity last, but hit the ground frist.
What happens as an object falls from earth?
the velocity of the object increases until it hits the ground
If a brick falls from the top of a building and strikes the ground with a velocity of 39.2 meters per second down how long does the brick fall?
Acceleration of gravity = 9.8 m/sec2.39.2 / 9.8 = 4 seconds

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 freely from rest. What is its velocity after 8 seconds?
78.4 m/s
Describe a situation in which gravity cause a change in velocity?

An apple falls from a tree and reaches the ground in 4 seconds with a velocity of 40m/s. What is the acceleration?
Using the acceleration formula, final acceleration is the final velocity minus the initial velocity over elapsed time. Final velocity you gave as 40m/s, and the initial velocity was zero (the apple was stationary on the tree), so the difference is 40 m/s. Divided by the time you gave, 4 s, this will be 10 m/sĀ²
Why does a stream of water get narrower as it falls from a faucet?
It is because velocity is inversely proportional to the cross-sectional area. As the water runs down from the faucet it changes velocity because of the pull of gravity, hence the liquid will be narrower as it falls down the ground.
If a skydiver has a starting velocity of 2 meter per seconds and falls straight down with no friction what is her velocity 5 seconds later?
v = vo + gt = 2(m/s) + 9.8(m/s2) x 5s = 51(m/s)
An apple falls from a tree What is its velocity after 1.6 seconds?
The acceleration of gravity is 9.8 meters per second2 downward. 1.6 seconds after falling from a branch near the surface of the Earth, the apple's speed is 15.68 meters per second. It's velocity is 15.68 meters per second downward. The tree has to be really tall, since the apple falls 12.544 meters (about 41 feet) in 1.6 seconds.
A bullet fired horizontally over level ground hits the ground in 0.5 seconds If it had been fired with twice the speed in the same direction it would have hit the ground when?
Assuming no affects from air and a smooth geography, both bullets would fall at the same rate of 9.81 m/s^2 toward earth, and hit the ground simultaneously. You have to look at the bullet's velocity as having a horizontal and vertical velocity vectors. The vertical velocity vector is independent from that of the horizontal. The horizontal vector would be the speed at which the bullet is fired, and the vertical vector is the speed at which the bullet falls due to gravity.
