### Part A
**Objective:**
Determine the angular acceleration of link \( CD \), measured counterclockwise.
**Instructions:**
Express your answer in radians per second squared to three significant figures. Enter a positive value if the angular acceleration is counterclockwise and a negative value if the angular acceleration is clockwise.
#### Formula Input:
\[ \alpha_{CD} = \, \text{[input box]} \, \text{rad/s}^2 \]

**Additional Information:**
- **Link \( AB \) Data:**
- Angular Velocity (\( \omega_{AB} \)) = 3.5 rad/s
- Angular Acceleration (\( \alpha_{AB} \)) = 9 rad/s\(^2\)
- See Figure 1 for reference.
- **Figure Description:**
The diagram illustrates a mechanical linkage system consisting of links \( AB \), \( BC \), and \( CD \). The setup is as follows:
- Link \( AB \) is positioned horizontally, with its motion described by the given angular velocity and acceleration.
- Point \( B \) is connected to link \( BC \), which is vertical with a length of 0.5 m between points \( B \) and \( C \).
- Link \( CD \) is horizontal, extending 1 m from point \( C \) to point \( D \).
Blue circular arrows near link \( AB \) indicate its angular motion parameters. The system's geometry and the positioning of the links are key to determining the derived angular acceleration of link \( CD \).
