Answer
The car has constant velocity during the section of the graph where the velocity is constant. This is represented by the segment from point Q to point R (QR) where the velocity remains at a constant value.

Answer
The greatest acceleration occurs during the section of the graph where the slope is steepest. This is indicated in the graph during the segment PQ, where the velocity increases rapidly. Therefore, PQ shows the greatest acceleration.
