Answer:
<em>The package will be traveling at 44.3 m/s when it hits the ground</em>
Explanation:
<u>Free Fall Motion</u>
A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not encounter air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is .
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The distance traveled by a dropped object is:
If we know the height h from which the object was dropped, we can find the time it takes fo hit the ground:
The package was dropped from h=100 m, thus the time taken to reach the ground is:
The final speed is now calculated:
The package will be traveling at 44.3 m/s when it hits the ground
