Answer:
Step-by-step explanation:
We know that the equation that models the height of the ball as a function of time is .
Where the initial speed is 80 feet.
When the ball lands on the ground, its height will be .
So to know how long it will take the ball to reach the ground, equal h (t) to zero and solve for t.
To solve this quadratic equation we use the quadratic formula.
For an equation of the form:
The quadratic formula is:
In this case
Then
We take the positive solution
