A student throws a ball in the positive direction vertically upwards. The ball makes an elastic collision with the ceiling, rebounds and accelerates back to the student's hand in a time of 1.2 s. Which graph best represents the acceleration of the ball from the moment it leaves the hand to the instant just before it returns to the hand?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AGraph showing acceleration starts constant positive, then drops to constant negative, then a brief positive spike, then constant negative until 1.2s.
BGraph showing acceleration starts constant positive, then drops to constant negative until 1.2s.
CGraph showing acceleration starts constant negative, then rises to constant positive, then a brief negative spike, then constant positive until 1.2s.
DGraph showing acceleration starts constant negative, then a brief positive spike, then constant negative until 1.2s.
✓ Correct answer
D: Graph showing acceleration starts constant negative, then a brief positive spike, then constant negative until 1.2s.
