Answer

The velocity of the object when it hits the ground is approximately 80.50 ft/s.

Explanation

## Step 1:We are given the formula for the velocity of an object dropped from a height , which is , where is the gravitational constant and is the height from which the object is dropped.## Step 2:We are given that ft and ft/s². We need to substitute these values into the formula to find the velocity when the object hits the ground.## Step 3:Substitute the given values into the formula, we get .## Step 4:Perform the multiplication and square root operations to find the value of .## Step 5:Round the calculated value to two decimal places as instructed in the question.
