D = 1/2 g T2
T = sqrt(2D/g) = sqrt( 109.2 / 9.8 ) = 3.335 seconds(rounded)

What would be the change for a 10 gram object dropped from a 20 meter building if it takes 2 seconds to reach the ground?
There is no reason for the object to change.
Does the mass effect the time taken for objects rolling down a slope?
Galileo dropped two different sized objects from the tower of Pisa and they both hit the ground at the same time. The object was to prove that the size/weight (i.e. mass) of the object would not affect the rate of fall.
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²?
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
What would be the displacement of an object going 5 meters north and then another 10 meters north?
15 meters north. the object is only moving away from the original starting place. its not like its moving away and then back again.
Would a ball dropped from 5 feet on the moon hit the ground faster that a ball dropped from five feet on the earth?
No, it would hit slower because gravity on the moon is 1/6 the gravity on earth.
What would be the change for a 10 gram object dropped from a 20 meter building if it takes 2 seconds to reach the ground?
There is no reason for the object to change.
What is the instantaneous speed of an object 2 second after being dropped in a vacuum?
In a vacuum, the instantaneous speed of an object 2 seconds after being dropped would be approximately 19.6 m/s, as the acceleration due to gravity is 9.8 m/s^2 and the object would have been accelerating for 2 seconds.
How long would it take for a ball to hit the ground if dropped from the statue of liberty?
The ESB is much wider at its base than at its top, so no object dropped from its top would hit the sidewalk. HOWEVER, an object dropped from the height of the ESB would, if it experienced no air friction nor hit anything along the way, would hit the ground in 8.8 seconds. However, air friction would delay this by a few seconds, as a small ball would experience air resistance before that time.
When You Drop An Object From A Certain Height It Takes Time T To Reach The Ground With No Air Resistance. If You Dropped It From Three Times That Height How Long Would It Take To Reach The Ground?
When an object is dropped from a certain height, the time it takes to reach the ground is independent of the height (assuming no air resistance). Therefore, whether you drop the object from three times the initial height or the original height, it will still take the same time (T) to reach the ground.
What does gravity do to the path of an object that is thrown horiziontally?
It doesn't matter whether the object is thrown down, up, horizontally, or diagonally. Once it leaves the thrower's hand, it is accelerated downward by an amount equal to acceleration of gravity on the planet where this is all happening. On Earth, if you throw an object horizontally, it accelerates downward at the rate of 9.8 meters per second2 ... just as it would if you simply dropped it. Whether it's dropped or thrown horizontally, it hits the ground at the same time.
Is it true an object that will hit the ground before an object that is thrown horizontally?
No, objects fall at the same rate regardless of their horizontal velocity. Both objects would hit the ground at the same time if dropped from the same height.
How will a package look after it was dropped from an airplane?
That would depend on the package, its contents and how it is wrapped. An empty, sturdy box will soon achieve terminal speed and look much like the box would after being dropped from a height of a few meters. A poorly wrapped heavy object would be seriously damaged.
Does uniform negative acceleration properly characterize the motion of a heavy object thrown violently downward from a tall building?
Yes, uniform negative acceleration (specifically gravity) can accurately describe the motion of a heavy object thrown downward from a tall building. The object would experience a constant acceleration due to gravity as it falls towards the ground. This acceleration would cause the object's velocity to increase over time until it reaches the ground.
Does a ball dropped with horizontal velocity take longer to hit the ground than on dropped at rest?
No, both balls will hit the ground at the same time, assuming they are dropped from the same height and in a vacuum. The horizontal velocity does not affect the time it takes for an object to fall vertically due to gravity.
How do two energy types transfer from one to another?
the 2 types are known as potential and kinetic if an object is held , high up, it has a form of potential energy due to its mass, and gravity , if the object is then dropped , it increases speed as it reached the ground, and its potential energy would be its greatest amount , when the object hits the ground, the moment it does so; the potential energy is changed or converted into kinetic, which transferrs the power to the ground and is converted into a form of " sound "
Which would hit the ground first a tennis ball or a baseball?
They would both hit at the exact same time; if you let them go at the exact same time.
Velocity time graph for a body dropped from a certain height?
The velocity-time graph for a body dropped from a certain height would show an initial spike in velocity as the object accelerates due to gravity, reaching a maximum velocity when air resistance equals the force of gravity. After this, the velocity would remain constant, representing free fall with a terminal velocity. When the object hits the ground, the velocity suddenly drops to zero.
