Answer: The ball will hit the ground 4 seconds after being thrown.
Step-by-step explanation:
By definition, the ball hits the grounds when the height is zero.
Then, knowing that the Quadratic function that models that situation is:
You can make it equal to zero:
Now you can use the Quadratic formula:
In this case you can identify that:
Therefore, knowing these values, you can substitute them into the Quadratic formula and then evaluate, in order to find the solution:
Choose the positive solution.
Then, the ball will hit the ground 4 seconds after being thrown.
