### Problem Statement

At a certain instant, the velocity of cylinder \( B \) is 1.26 m/s down and its acceleration is 2.07 m/s² up. Determine the corresponding velocity and acceleration of block \( A \). The velocity and acceleration of \( A \) are positive if down the slope and negative if up the slope.

### Diagram Explanation

The diagram illustrates a mechanical system consisting of two blocks \( A \) and \( B \). Block \( A \) is placed on an inclined plane and connected to a pulley system, which in turn is connected to block \( B \). The system of pulleys influences the motion of block \( A \) based on the movement of cylinder \( B \). Block \( A \) is connected to one end of the rope which passes through several pulleys before it is attached to the hanging block \( B \).

### Given Data

- Velocity of \( B \) (\( v_B \)): 1.26 m/s (down)
- Acceleration of \( B \) (\( a_B \)): 2.07 m/s² (up)

### Required

Determine the velocity (\( v_A \)) and acceleration (\( a_A \)) of block \( A \).

### Answers Section

The answers section provides input fields for students to calculate and insert the values for the velocity and acceleration of block \( A \).

#### Velocity of \( A \) (\( v_A \))
\[ v_A = \_\_\_\_\_ \text{ m/s} \]

#### Acceleration of \( A \) (\( a_A \))
\[ a_A = \_\_\_\_\_ \text{ m/s}^2 \]
