For this case we have the following function:
To find the time when it reaches its maximum height, what we must do is to derive the function.
We have then:
We set zero and clear the time:
Then, we evaluate the time obtained for the function of the height.
We have then:
It will take the rocket to reach its maximum height:
the maximum height is:
