**Figure Description:**
The image shows a mechanical setup involving a wheel, a rod, and a slider block. The slider block moves with the motion shown, where:
- \( r = 140 \, \text{mm} \)
- \( h = 500 \, \text{mm} \)
The wheel is labeled at point \( A \) and is connected to a point \( B \) on the slider block. The velocity (\( v_B \)) and acceleration (\( a_B \)) at point \( B \) are given as:
- \( v_B = 4 \, \text{m/s} \)
- \( a_B = 2 \, \text{m/s}^2 \)
**Problem Description:**
**Part A**
Determine the angular velocity of the wheel at this instant measured counterclockwise.
- 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.
Input Interface:
- Angular Velocity (\( \omega \)) = [Input Box] rad/s
- Button: Submit

**Part B**
Determine the angular acceleration of the wheel at this instant measured counterclockwise.
- Express your answer using three significant figures.
- Enter a positive value if the angular acceleration is counterclockwise and a negative value if the angular acceleration is clockwise.
Input Interface:
- Angular Acceleration (\( \alpha \)) = [Input Box] rad/s\(^2\)
