A ball initially at rest is dropped from a window 24.3 m off the ground. How long does it take for the ball to reach the ground?

The ball takes 2.23 seconds to reach the ground

Explanation:

Free Fall Motion

A free-falling object falls under the influence of gravity only. An object being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not have 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 distance traveled by a dropped object is:

Knowing the height h from which the object was dropped, we can find the time it takes fo hit the ground:

Since y=24.3 m:

t=2.23 seconds

The ball takes 2.23 seconds to reach the ground
