#### Figure Description:
- The diagram illustrates a mechanical system with rods \( AB \), \( BC \), and \( CD \).
- Rod \( CD \) is at an angle of 30° with the horizontal.
- The length of rod \( AB \) is 1 meter.
- The length of rod \( BC \) is 0.4 meters.
- The length of segment \( DC \) is 0.5 meters.

### Part A:
Determine the angular velocity of the rod \( AB \) at the instant shown, measured clockwise.

- **Input Field**: \( \omega_{AB} = \) ______ rad/s
- Express your answer using three significant figures. Enter a positive value if the angular velocity is clockwise and a negative value if the angular velocity is counterclockwise.
- Buttons provided for vector notation and other mathematical symbols.
- **Action Buttons**: Submit, Request Answer

### Part B:
Determine the angular velocity of the rod \( CB \) at the instant shown, measured counterclockwise.

- **Input Field**: \( \omega_{CB} = \) ______ rad/s
