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.

How far will a freely falling object fall from rest in 4 seconds?
78.46 meters (257.4 feet)
How far will a freely falling object dropped from rest in eight seconds?
Assuming the object free-falls, we may use:x = x0 + v0t + at2/2x0 = 0 (we determine it)v0t = 0 (dropped from rest).a = g = 10 m/st2 = 16s2.x = 10*16 / 2 = 80m.

What is the speed of a free falling object after ten seconds from rest?
It depends on the object's mass.
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?
X = 1/2 G t2t = sqrt( 2X/G )= sqrt ( 200/9.8 )= sqrt (20.408 )= 4.518 seconds (rounded)

An object is dropped from rest at a height of 128 m. Find the distance it falls during its final second in the air.?
If an object is dropped from rest at a height of 128 m, the distance it falls during its final second in the air is still 128 m.
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.
It takes 6 seconds for a stone dropped from rest to hit the bottom of a well what is its final speed?
60 m/s
