Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form

So
the t coordinate of the vertice is:

In this case the equation is:

So

Therefore


Finally the maximum height that the ball will reach is
