Final answer:
At the instant the displacement of a 2.00kg object is zero.
Step-by-step explanation:
The correct answer is
A) object is zero.
At the instant the displacement of a 2.00kg object is zero, it means that the object is not moving and its velocity is zero. This can occur when the object is at rest or when it reaches a point where its displacement is neither increasing nor decreasing. For example, if an object is dropped from a height, at the instant it hits the ground its displacement is zero.
