Answer 1

In this problem, we want to answer an application problem including velocity.

We are given

`v=√(19.6h)`

where v represents the velocity and h represents the height in meters.

If we are dropping an object from a height of 22.3 meters, we want to know the velocity when it hits the ground.

We can subsitute the value of h into the formula to get:

`v=√(19.6(22.3))\approx20.9`

So, the velocity will be 20.9 meters per second.
