Explanation:

Step1: Recall circular - motion acceleration

In uniform circular motion, the acceleration is centripetal acceleration.

Step2: Determine direction at bottom

At the bottom of the circular track, centripetal acceleration points towards the center of the circle, which is upward.

Answer:

upward
