The traditional acceleration due to gravity (9.8
meters per second per second) is assuming a vacuum. However, for short
falls, it works out well.
For longer falls, the force of gravity is eventually equaled by the force of
air resistance. At this time the speed remains constant. As you are likely
aware, in order to have a change in velocity, an unbalanced force is
required.
The "terminal velocity" is determined by the shape of the object. Sky
divers can speed up and slow down by changing the shape they present to the
relative wind (the air going by them). Ultimately, they open their
parachute and greatly increase the for of the air resistance... (luckily!)
slowing them down considerably.

An object with a mass of 8 kg is dropped and takes 2 s to hit the ground. Then another object with a mass of 16 kg is dropped from the same point. How long does it take to hit the ground?
2s
How long in seconds would it take for an object to fall 120 meters?
depends on weight of object and wind strength.normally heavy objects will drop down faster than lighter objects.
How long does it it take an object of 4 kg to hit the ground considering another object with a mass of 2 kg took 3 seconds to hit the ground?
Assuming they were in a vacuum, if both objects were dropped from th esame height, then both take the same length of time to reach the ground. All masses fall with the same acceleration, reach the same speed in the same period of time, and hit the ground at the same time. Otherwise and if there is an atmosphere or if they are dropped from different heights, you have not presented information; shape and size are the most important factors.
How long would it take for an object dropped from 54.6 meters to hit the ground?
D = 1/2 g T2T = sqrt(2D/g) = sqrt( 109.2 / 9.8 ) = 3.335 seconds(rounded)
How long does it take an object with a velocity of 2.5 meters a second up to fall 15m?
15 m divided by 2.5 m s-1 is 6 s.
How long will it take an object dropped from a window to fall a distance of 78.4 meters?
4 Seconds
Does an object dropped from twice as high take twice the time to fall?
No. Objects falling on Earth in a vacuum fall at an increasing speed of 32 feet per second per second and the same object dropped from the higher level will be traveling faster during the second half of its fall, thereby it will take less than twice the time required to fall half the distance.
How long will it take an object dropped from a height of 500 feet to hit the ground?
4 seconds
An object with a mass of 8 kg is dropped and takes 2 s to hit the ground. Then another object with a mass of 16 kg is dropped from the same point. How long does it take to hit the ground?

A stone is dropped from the edge of the roofHow long does it take to fall 9.8m?
It depends on how much the stone weigh. And how tall the roof is...
How long would it take to fall if you dropped all the water in the world on top of new york city but funneled it so it could only fall in that one spot?
Five minutes
If you fall 25 ft how long will it take to hit the ground?
Assuming you have the same mass you could use the formula h=-16t^ 2+ c H stands for height of falling object after time c stands for height dropped from t stands for time
How long will it take an object dropped off the Leaning Tower of Pisa to reach the ground?
It depends plus, you can't go to the top of the leaning tower of Pisa.
How long in seconds would it take for an object to fall 120 meters?
depends on weight of object and wind strength.normally heavy objects will drop down faster than lighter objects.
How do you get rid of a black toenail?
Usually they just have to grow out, which, frustratingly, can take a number of months.
How long does it take for felt to fall?
It depends from how high and the weight of it but the acceleration will be 9.8m/s2 if gravity is the only force acting upon the object.
How does gravity make things fall?
The weight of the object causes gravity to take the object falling
