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.
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 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.
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.
If an object free-falls for 2.6 seconds what will be its final velocity and how far will it fall?
The final velocity of an object in free-fall after 2.6 seconds is approximately 25.48 m/s. The distance the object will fall during this time is approximately 33 meters.
How far in feet does an object fall in 2 seconds?
An object in free fall will fall approximately 64 feet in 2 seconds.
How does the weight of an object affect the way it falls?
The weight of an object does not affect the way it falls. In a vacuum, objects of different weights fall at the same rate due to gravity. In an atmosphere, air resistance can affect the rate at which an object falls, but the weight of the object itself does not play a significant role.
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.
An example of free fall?
An example of free fall is when an object is dropped from a height without any initial horizontal velocity. During free fall, the only force acting on the object is gravity, causing it to accelerate towards the ground at a rate of 9.8 m/s^2. This is commonly seen when objects like skydivers, parachutists, or a dropped ball fall towards the Earth.
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.
When an object released from rest and falls at rest in the absence of friction what is true about its motion?
If an object is released from rest and falls at rest in the absence of friction, it means that the object is in free fall. During this process, the object accelerates due to the force of gravity until it reaches its terminal velocity when air resistance equals the gravitational force acting on the object.
What speed of object falling from 250 feet to earth?
The time it takes for an object to fall from a height of 250 feet to Earth depends on the acceleration due to gravity. Assuming a standard value of 9.81 m/s^2 for gravity, it would take approximately 3.2 seconds for the object to fall. The speed at which the object would impact the ground can be calculated using the equation for free fall: v = sqrt(2gh), where v is the final velocity, g is gravity, and h is the height.
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.
Why does object fall when it goes up?
An object falls back to Earth because of gravity.
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.
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.
