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

Step-by-step explanation:
Our expression is: .
Let's focus on the cube root of 81 first. What's the prime factorisation of 81? It's simply: 3 * 3 * 3 * 3, or . Put this in for 81:
We know that the cube root of 3 cubed will cancel out to become 3, but the cube root of 3 cannot be further simplified, so we keep that. Our outcome is then:
Now, let's multiply this by 1/3, as shown in the original problem:
Thus, the answer is .
