Responses

The velocity is constant and non-zero.
The velocity is constant and non-zero.

The velocity is zero.
The velocity is zero.

The acceleration is constant and non-zero.
The acceleration is constant and non-zero.

The acceleration is negative.

Answer 1

The velocity is zero.

Reason: The slope of a position vs. time graph gives velocity; a horizontal line has slope 0, so the object's velocity is zero (it is at rest).
