Answer
The car has constant velocity during the section where the line is horizontal. Referring to the graph, this occurs in section PQ, where the velocity remains steady at 10 m/s for the duration. Therefore, the correct answer is:
A PQ

Answer
The greatest acceleration is indicated by the steepest slope of the velocity graph. From the graph, this occurs during section QR, where the velocity increases rapidly. Thus, the correct answer is:
