#### Answer:

As the speed is the derivative of the position function, at

#### Explanation:

I have to assume you are working with calculus in this Physics course. The first derivative of the position with respect to time will give the velocity function:

If we evaluate this function at

The object has (momentarily) stopped at

And, for the record, its acceleration is the second derivative of
