Examiners report
Many candidates answered this question completely and correctly, showing a good understanding of the graphical relationship between displacement, velocity and acceleration. When done incorrectly, many answered with the displacement as graph B and acceleration as graph C.
Many candidates found the value of t which gave a maximum in the remaining graph, and were awarded follow through marks.
