Step-by-step explanation:
The path covered by the volleyball will be a downward parabola with the vertex being the highest point of the ball.

Where  is the vertex of the parabola and 'a' is a constant.
 is the vertex of the parabola and 'a' is a constant.
Now, let 'h' be the vertical height and 't' be the time taken.
So, the equation would be of the form:

Now, as per question:
h = 2 seconds, k = 13 feet.

Now, taking a = 1. So, the formula that can be used is:
