**Problem Statement:**

The block \( C \) is moving downwards at the speed shown. Find the speed of \( B \) and the angular velocity of links \( CB \) and \( AB \).

**Diagram Description:**

The diagram illustrates a system involving a block \( C \) and links \( CB \) and \( AB \). The details are as follows:

- Block \( C \) is moving downward at a velocity \( v_c = 2.5 \, \text{ft/s} \).
- Link \( CB \) is inclined at an angle of \( 30^\circ \) from the horizontal.
- The length of link \( CB \) is \( 3 \, \text{ft} \).
- Link \( AB \) is horizontal, and its length is \( 2 \, \text{ft} \).
- Point \( A \) is fixed, allowing rotation around it.
- The direction of angular motion is indicated around point \( A \).

The problem requires calculating the velocity of point \( B \) and the angular velocities of links \( CB \) and \( AB \).
