**Problem Statement:**

At a given instant, the roller \( A \) on the bar has the velocity \( v = 3 \, \text{m/s} \) and acceleration \( a = 6.5 \, \text{m/s}^2 \). 

**Figure Explanation:**

The diagram shows a bar positioned at an angle. Roller \( A \) is located at the top end of the bar, moving vertically downward, with the specified velocity and acceleration. Roller \( B \) is at the other end of the bar, which is at an angle of \( 30^\circ \) to the horizontal ground. The length of the bar between \( A \) and \( B \) is \( 0.6 \, \text{m} \).

Axes are denoted by \( x \) and \( y \), with \( x \) being horizontal and \( y \) being vertical.

**Tasks:**

- **Part A:**
  - Determine the velocity of the roller \( B \) at this instant.
  - Express your answer to three significant figures and include the appropriate units.

  Input box represented by:
  \[
  (v_B)_x = \text{Value} \, \text{Units}
  \]

- **Part B:**
  - Determine the acceleration of the roller \( B \) at this instant.
  - Express your answer to three significant figures and include the appropriate units.

  Input box represented by:
  \[
  (a_B)_x = \text{Value} \, \text{Units}
  \]
