Astone is dropped from rest from a tall building how fast is the stone moving after 5s

The final velocity is -49.05 meters per second.

Explanation:

Let's use an equation of constant acceleration:

Where a is the acceleration and g is the acceleration caused by gravity.

Since the object is being dropped from rest, .

We're looking for the speed after 5 seconds, so .

So the final velocity is -49.05 meters per second.
