All objects in free fall experience an acceleration due to gravity of 32 m/s² at all times. Some basic knowledge of physics gives us the equation
d=vi*t+1/2*a*t²
Where d is the distance traveled, vi is the initial velocity, t is the time of travel and a is the acceleration. Plugging in the values vi=0 (meaning theres no initial velocity), t=5.2s and a=-32m/s² (negative because gravity pulls you downward) we get the equation
d=0*5.2s + 1/2 * (-32 m/s²) * (5.2s)²
Which when simplified tells us that the distance fallen is 432.64 feet.
However, in real life, friction means that we will never get an answer as nice as this. Friction constantly opposes the motion of any moving object, meaning that in a given time less distance will be covered than estimated by this equation. Sadly, without knowing more about the object (its shape, mass, and composition) there's no way to calculate how much effect friction will have.

What is the distance covered by a freely falling object 5 seconds after it is dropped from rest?
0.7848 meter
A rock is dropped from a height of 60 m and is in a free fall what is the velocity of the rock as it reaches the ground 3.5 seconds later?
After 3.5 seconds of free-fall on or near the surface of the Earth, (ignoring effectsof air resistance), the vertical speed of an object starting from rest isg T = 3.5 g = 3.5 x 9.8 = 34.3 meters per second.With no initial horizontal component, the direction of such an object's velocitywhen it hits the ground is straight down.
What is the acceleration by a freely falling object 5 seconds after it is dropped from rest?
It depends if it is affected by air resistance or not. If not then all objects close to the surface of the Earth have an acceleration of 9.81ms^-2 in free fall. If it is affected by air resistance you need all sorts of more information to answer that question, like the drag coefficient of the air.
What is the speed of an object in free fall 2 seconds after falling from rest?
Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
What is speed of object at 3 seconds given an acceleration of 16 feet per second squared for 3 seconds?
I assume the object starts from rest. The speed will be 16*3 which is 48m/s
What is the distance covered by a freely falling object 5 seconds after it is dropped from rest?
0.7848 meter
An 8-kg mass is in free fall. what is the velocity of the mass after 9 seconds?
An object dropped from rest will have a downward velocity of (9 g) = 88.2 meters per second after 9 seconds. Ignoring air resistance, the mass of the object is irrelevant. All masses fall with the same acceleration, and have the same downward velocity after any given period of time.
What is the velocity of an object that started from rest and has been in free fall for 10 seconds?
The velocity of an object in free fall after 10 seconds is approximately 98 m/s. This value is the acceleration due to gravity (9.8 m/s^2) multiplied by the time in seconds.
How far does an object fall in .25 seconds?
Assuming the object starts from rest, the distance an object falls in 0.25 seconds can be calculated using the equation ( d = \frac{1}{2}gt^2 ), where (d) is the distance, (g) is the acceleration due to gravity (9.8 m/sĀ²), and (t) is the time. Substituting the values, the object would fall approximately 0.31 meters in 0.25 seconds.
A rock is dropped from a height of 60 m and is in a free fall what is the velocity of the rock as it reaches the ground 3.5 seconds later?
After 3.5 seconds of free-fall on or near the surface of the Earth, (ignoring effectsof air resistance), the vertical speed of an object starting from rest isg T = 3.5 g = 3.5 x 9.8 = 34.3 meters per second.With no initial horizontal component, the direction of such an object's velocitywhen it hits the ground is straight down.
An object is dropped from rest from the top of a 100 m building How long will it take for the object to hit the ground?
The time it takes for an object to fall from rest can be calculated using the formula: time = sqrt(2h/g), where h is the height (100 m) and g is the acceleration due to gravity (9.81 m/s^2). Plugging in the values gives a time of about 4.51 seconds.
How far will a freely falling object dropped from rest in eight seconds?
Assuming constant acceleration due to gravity, the object will fall a distance of 313.6 meters in 8 seconds. This is calculated using the formula ( d = \frac{1}{2} g t^2 ), where ( d ) is the distance fallen, ( g ) is the acceleration due to gravity (approximately 9.81 m/s(^2)), and ( t ) is the time elapsed.
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.
What is the acceleration by a freely falling object 5 seconds after it is dropped from rest?

An 8 kg mass is in free fall What is the velocity of the mass after 9 seconds?
The velocity of an object in free fall can be calculated using the equation v = gt, where g is the acceleration due to gravity (9.8 m/s^2). Plugging in the values, we get v = 9.8 m/s^2 * 9 s = 88.2 m/s. Therefore, the velocity of the 8 kg mass after 9 seconds is 88.2 m/s.
Ten seconds after starting from rest a free falling oblect speed ms?
After 10 seconds of free fall from rest, an object's speed will be approximately 100 m/s. This is because the acceleration due to gravity is approximately 10 m/s^2, so after 10 seconds, the object will have reached a speed of 100 m/s.
