If an object is released from rest and falls for 5 seconds How far did the object fall?

For this we calculation must consider the equation
s=uv + 1/2 at2
Where s = displacement, u= initial velocity, v= velocity, a= acceleration & t=time.
Since initial velocity is is at rest hence 0 we can ignore the uv.
Also the acceleration is gravity or g.
So therefore
s=1/2 gt2
For earth g= 9.812865328 m/s
and t= 5 s
so
s= 1/2*9.812865328*(5)2
s= 122.66m
This answer of course does not take into consideration wind resistance.

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.
How many feet will a 100 pound object fall in 7 seconds?
Any object near the surface of the earth, falling without air resistance and under the influence of only gravity, falls 789 feet. (rounded) Its weight makes no difference.
When two objects of different masses released from a height under normal conditions which object falls first?
Answer #1:Under normal circumstances the less aerodynamic object will fall first. Mass has no direct effect except in the way that it affects the coefficient of drag.===========================Answer #2:If not released at the same time, then the object released first falls first. If both released at the same time, then see Answer #1 above for a detailed description of their behavior.
How fast does an object fall if it takes 3 seconds to drop 200 feet?
45.5 mph
How far does a free falling object fall per second?
Every second, it falls farther and faster than it fell in the previous second.
An example of free fall?
A planet orbiting the Sun.A heavy object, released, to let it fall (for the first few seconds; later, air resistance may be significant).A planet orbiting the Sun.A heavy object, released, to let it fall (for the first few seconds; later, air resistance may be significant).A planet orbiting the Sun.A heavy object, released, to let it fall (for the first few seconds; later, air resistance may be significant).A planet orbiting the Sun.A heavy object, released, to let it fall (for the first few seconds; later, air resistance may be significant).
If an object falls for 12 seconds from what height did it fall ignoring air resistance?
On object falling under the force of gravity (9.8 m/s2) would, in a vacuum, fall a distance of 706 metres in 12 seconds. In a non-vacuum, i.e. air, the object would fall less distance in the same time due to drag.xt = 0.5 (9.8) t2
What speed of object falling from 250 feet to earth?
The speed of a falling object keeps changing as it falls. If an object falls 250 feet to the ground and there is no air, then it takes about 4 seconds to fall, and it hits the ground at about 86.5 miles per hour (127 fps). If the object falls through air, then the speed it picks up depends on its weight and shape ... a sailplane falls slower through air than a rock does, but take away the air, and a rock and a feather fall together.

Why does object fall when it goes up?
An object falls back to Earth because of gravity.
How long would it take to fall 167 feet?
Surely you're aware that a falling object accelerates under the influence of gravity. That acceleration manifests itself in the form of steadily-increasing speed, so the time required to fall 186 feet depends on how long it has already been falling. -- Immediately after it's dropped, the object falls the first 186 feet in 3.399 seconds. -- It falls the NEXT 186 feet in 1.408 seconds. -- It falls the next 186 feet in 1.08 seconds. -- It falls the next 186 feet in 0.911 second. -- It falls the next 186 feet in 0.802 second. . . etc.
How many seconds has ball to fall in hole?
After you put if the ball is on the edge of the hole it has 10 seconds to fall in. If it falls in after that you must take another stroke.
A rock falls from a cliff 144 ft high How long does it take the rock to reach the ground?
an object will fall at around 50ft every second, so around 3 seconds.
What is the definition of free-falling parchute?
"Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored. An open parachute does not normally fall in this category."Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored.

What force causes an object to fall once it is released?
Gravity causes an object to fall to Earth.
How does the weight of an object affect the way it falls?
Yes. Because paper is much much lighter than a bowling ball so if you drop them the paper will take atleast 1.3 seconds to fall and a bowling ball will take atleast 0.5 seconds.
