 For this problem, refer to the figure on the right.

 
   What is the direction of the angular acceleration of the disk shown?
  -x axis   
  -z axis   
  -y axis   
  +z axis   
  +y axis   
  +x axis   
**Diagram Explanation**

This diagram illustrates a circular motion scenario where an object is depicted as a black dot moving counter-clockwise along a circular path indicated by the curved arrow. The diagram is labeled "Slowing Down," suggesting that the speed of rotation is decreasing.

**Coordinate Axes**

To the right of the circular path, there is a 3D coordinate axes illustration:
- **x-axis**: Points horizontally to the right.
- **y-axis**: Points vertically upwards.
- **z-axis**: Dashed arrow pointing out of the page.

This setup suggests a right-hand coordinate system commonly used in physics to describe rotational motion in three dimensions. The information provided suggests that the rotational velocity is decreasing (hence "slowing down"), possibly due to an external force like friction or air resistance. The z-axis orientation indicates the direction of angular momentum about the center of rotation, which is perpendicular to the plane of motion.
