**Physics Problem: Three-Mass Pulley System**

**Problem Description:**

Three objects with masses \( m_1 = 7.4 \, \text{kg} \), \( m_2 = 11 \, \text{kg} \), and \( m_3 = 19 \, \text{kg} \), respectively, are attached by strings over frictionless pulleys as shown in the figure below. The horizontal surface exerts a force of friction of 30 N on \( m_2 \). If the system is released from rest, use energy concepts to find the speed of \( m_3 \) after it moves down 4.0 m.

**Diagram Explanation:**

The diagram shows a classic physics pulley system:

- \( m_1 \) and \( m_3 \) are hanging on either side of the table, connected by a string over the pulleys.
- \( m_2 \) is on the table, connected to the other two masses by the same string.
- The table surface is horizontal, and a frictional force acts on \( m_2 \).

The task is to calculate the velocity of \( m_3 \) after it descends 4.0 meters, considering gravitational forces, friction, and conservation of energy principles.
