I think it would depend on how much the object weighed, wouldn't it? Like Bowling ball vs. wiffle ball?

-------

The above answer is incorrect. The object falls about 125 meters or roughly 410 feet if it has little or no air resistance.

More detail is available below.

-------

The following equation assumes there is no air resistance, but that can severely affect results. A penny of the same weight as a feather clearly falls faster, as the feather has more cross-sectional area.

Like the above example for instance: a wiffle ball's rough and uneven surface has more air resistance than the bowling ball's slick surface, so it doesn't accelerate as quickly and also reaches its terminal velocity more quickly.

It also assumes that the object has no initial speed. A ball thrown downwards clearly would go farther than one that was dropped.

The equation is

d=(1/2)(a)(t2)

where [d] is distance, [a] is acceleration (acceleration due to gravity is considered to be roughly 9.8 meters per seconds squared or 10 m/s), and [t] is the time.

If we plug and chug...

d=(1/2)(10)(52)

d=(5)(25)

d=125

That's 125 meters, or roughly 410 feet.

A freely falling object will fall approximately 122.5 meters from rest in five seconds under the influence of gravity. This value is based on the acceleration due to gravity, which is approximately 9.81 m/s^2.

15 meters

We can use the equation v2 = v02+2ax to find out how fast the object is moving after the first interval of time (a = 9.8 m/s2, which is acceleration due to gravity):

v2 = 0 + 2(9.8)(5)

v2 = 98

v = √98

v = 9.8995 (approx.)

We can then use the equation v = v0+at to find the time it took to fall 5 meters (and therefore the length of an interval):

√98 = 0 + (9.8)t

t = (√98)/9.8

t = 1.0102 (approx.)

Finally we can use the equation x = v0t+(1/2)at2 to calculate how far it fell during the second (√98)/9.8 seconds.

x = (9.8955)(1.0102) + (1/2)(9.8)(1.0102)2

x = 15.00 meters

this depends on the mass and weight of said object.

============================================

500 years of human inquiry and achievement down the drain !

It has nothing to do with the mass or weight of said object.

If they are truly "free falling", then a feather and a battleship will accelerate at the

same rate, and will have the same speed after 5 seconds.

If this drama is unfolding on or near the Earth, then that speed will be 49 meters

(160.8 feet) per second.

Since it started out being dropped with zero speed, its average speed during that

time is 24.5 meters per second, and the distance it falls during the first 5 seconds

after being dropped is (24.5 x 5) = 122.5 meters (401.9 feet).

On or near earth, the acceleration of gravity is 9.8 meters (32.2 feet) per second2 .

After 5 seconds of fall without air resistance, the speed of fall is

49 meters (160.8 feet) per second.

In order to answer this question it is necessary to assume that

  • the stone was at rest before it started falling;
  • it is falling under the force of the earth's gravity and no other force (it was not thrown);
  • air resistance can be ignored.

In that case, it will fall approx 44 metres.

Please use the formula:v = v0 + at

Where v0 is the initial velocity, a is the acceleration, and t is the time. The acceleration near Earth is approximately 9.8 meters per square second.

How far will a freely falling object fall from rest in 4 seconds?

Assuming the object is falling under gravity, it will fall approximately 78.4 meters in 4 seconds. This is based on the formula: distance = 0.5 x acceleration due to gravity x time squared.


What is speed of a freely falling object ten seconds after starting from rest?

The speed of a freely falling object 10 seconds after starting from rest is approximately 98 m/s. This is because in free fall, the acceleration due to gravity is approximately 9.8 m/s^2, so after 10 seconds, the object would have reached a speed of 98 m/s.


Does an object that is freely falling have mass?

Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.


How far will a freely falling object fall from rest in five?

122.5 meters (402.5 feet)


What is the definition of free fall?

when the acceleration of the freely falling object is equal to the acceleration due to gravity then there occurs free fall.


Suppose an object in free fall is dropped from a building Its starting velocity is 0 Ignoring the effects of air resistance what is the speed of the object after falling 3 seconds?

The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.


What Suppose an object in free fall is dropped from a building it and starting velocity is 0 ms what is the speed of the object after falling 2 seconds?

The speed of an object in free fall after falling for 2 seconds is approximately 19.6 m/s. This value is obtained by multiplying the acceleration due to gravity (9.8 m/s^2) by the time the object has been falling (2 seconds).


What is the only force acting on a freely falling object?

The only force acting on a freely falling object is gravity. This force causes the object to accelerate downward at a rate of 9.81 m/s^2 near the surface of the Earth.


What is the meaning of Free Falling?

Let's imagine there is no air resistance and that gravity is the only thing affecting a falling object. Such an object would then be in free fall. Freely falling objects are affected only by gravity


How fast in miles per hour would an object fall after 3 seconds?

At the end of 3 seconds, a falling object is falling at 65.8 mph faster than when it was released, ignoring air resistance.


Suppose an object in free fall is dropped from a building. Its starting velocity is 0 ms. What is the speed (in ms) of the object after falling 2 seconds Give your answer as a positive decimal.?

The speed of an object in free fall after falling for 2 seconds is approximately 19.6 m/s.


What is a falling object on which gravity is the only force?

An object falling freely under gravity is known as a free-falling object, where gravity is the only force acting on it. In the absence of other forces like air resistance, the object accelerates at a constant rate of 9.8 m/s^2 (approximately) towards the Earth's surface.
