Exercise question no. 3.10 part c.

When the ball is in upward motion, the acceleration on the ball is the acceleration due to gravity which acts vertically downward only.
Similarly, while ball is moving downward, the acceleration is the acceleration due to gravity acting downward.
Downward direction is taken as positive and hence acceleration is positive in both cases.
