For this case we have the following function that models the problem is:
The time for which the maximum height occurs is obtained by deriving the equation:
We equal zero and clear x:
The maximum height is obtained by evaluating the time obtained in the given equation:
Then, by the time it reaches the ground we have:
From here, we clear x solving the quadratic equation:
We discard the negative root, and obtain as a result:
