### Velocity Determination of Bodies in a Pulley System

#### Problem Statement:
At the instant represented, \( v_{B/A} = 2.8\mathbf{j} \, \text{m/s} \). Determine the velocity of each body at this instant. Assume that the upper surface of A remains horizontal.

#### Diagram Description:
The diagram below displays a pulley system with multiple pulleys and two bodies labeled A and B. 

- **Pulleys**: There are five pulleys shown in the system.
- **Body A**: This body is a large rectangular block connected to three pulleys via ropes.
- **Body B**: This is a smaller object connected to the rightmost pulley by a single rope.
- **Coordinates**: A coordinate system with x and y axes is provided, where the direction of the velocity \( v_{B/A} \) is along the y-axis (vertical direction).

#### Answers Section:
You are required to input the velocities of the bodies A and B.

- \( v_A = \_\_\_\_\_\_\_\_ \, \text{j m/s} \)
- \( v_B = \_\_\_\_\_\_\_\_ \, \text{j m/s} \)

**Note**: These velocities are to be calculated based on the given relationship \( v_{B/A} = 2.8\mathbf{j} \, \text{m/s} \).

To solve this problem, consider the properties of the pulley system and the relationships between the movements of each body. Use kinematic equations and constraints offered by the rope system to determine the individual velocities of bodies A and B.
