Pete is accelerating.
Pete remains still.
Pete has a position of zero.
Pete has a constant, nonzero velocity.

Answer 1

In the context of the graph showing Pete's journey, the horizontal line indicates that Pete is remaining still or stationary. This means that the distance from home does not change over time, indicating that there's no movement or velocity during that period. Therefore, the correct interpretation is:

Pete remains still.
