Question

Which situations can be modeled with a periodic function?

• A. Flag on windmill
• B. Height of baseball after being hit
• C. Ball suspended from string

Answer 1

The correct option is C

Ball suspended from string

Explanation for the the correct option:

Option $\left(C\right)$:

It is given that, a ball suspended from string.

As ball is attached to string so it returns back in constant interval.

We know that, when the function returns to its original value after particular intervals the function is called periodic function.

Hence it is periodic function.

Explanation for incorrect options:

Option $\left(A\right)$

It is given that, “a flag on wind mill”

As it is a constant function so it is not periodic.

Hence option $B$ is incorrect.

Option $\left(B\right)$:

It is given that, “height of baseball after being hit”

This function is changing as it will provide different values.

So it is not periodic.

Hence it is incorrect.

Hence, option $C$ is the correct answer.
