Explanation:

Step1: Recall acceleration definition

Acceleration is a change in velocity (speed and/or direction).

Step2: Analyze box of paper - clips

It is slowing down, so its speed is changing, thus it is accelerating.

Step3: Analyze box of jewelry

It is held still, so its velocity is zero and not changing, no acceleration.

Step4: Analyze box of cereal

It is moving at a steady speed in a straight - line, so no change in speed or direction, no acceleration.

A box of paper clips that is slowing down after being pushed across a wide desk.
