Solve correctly
![### Problem Statement
The assembly consists of two 25-kg bars that are pin-connected. The bars are released from rest when \( \theta = 60^\circ \). The 5-kg disk at \( C \) has a radius of 0.5 m and rolls without slipping.
#### Figure Description
- The diagram shows two bars, \( AB \) and \( BC \), forming a V-shape.
- Bar \( AB \) is connected to a pivot point at \( A \), and bar \( BC \) is connected to a rolling disk at \( C \).
- Each bar is 3 meters long.
- The angle \( \theta \) is shown between each bar and the horizontal ground, initially set at \( 60^\circ \).
### Questions
**Part A**
Determine the angular velocity of the bar \( AB \) at the instant \( \theta = 30^\circ \), measured clockwise.
- **Instructions**: 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.
\( \omega_{AB} = \) [Input Field] rad/s
**Part B**
Determine the angular velocity of the bar \( BC \) at the instant \( \theta = 30^\circ \), measured counterclockwise.
- **Instructions**: Express your answer using three significant figures. Enter a positive value if the angular velocity is counterclockwise and a negative value if the angular velocity is clockwise.
\( \omega_{BC} = \) [Input Field] rad/s
