Answer:

Step-by-step explanation:
We are given that
Initial velocity=30 ft/s
Initial position=
We have to write a mathematical model for height of the softball by using the position equation
The position equation on Earth's surface is given by

Where
Initial velocity
=Initial position
Substitute the values in the equation then, we get

Hence, the mathematical model for height of the softball is given by
