### Understanding the Motion of Center of Mass

#### Abstract
Understand that, for many purposes, a system can be treated as a point-like particle with its mass concentrated at the center of mass.

A complex system of objects, both point-like and extended ones, can often be treated as a point particle, located at the system's center of mass. Such an approach can greatly simplify problem-solving.

#### Problem Description
Recall that the blocks can only move along the x-axis. The x components of their velocities at a certain moment are \( v_{1x} \) and \( v_{2x} \). Find the x component of the velocity of the center of mass \((v_{\text{cm}})_x\) at that moment. Keep in mind that, in general: \( v_x = \frac{dx}{dt} \).

Express your answer in terms of \( m_1 \), \( m_2 \), \( v_{1x} \), and \( v_{2x} \).

##### Expression Input
\[ (v_{\text{cm}})_x = \]
\[ \begin{array}{|c|} \hline \\ \\ \\ \hline \end{array} \]

#### Figure Explanation

The figure depicts a horizontal axis representing the x-axis. There are two blocks:
- Block 1 with mass \( m_1 \) positioned at \( x_1 \).
- Block 2 with mass \( m_2 \) positioned at \( x_2 \).

#### Detailed Steps
1. **Identify the Masses and Positions**:
    - Mass of block 1: \( m_1 \).
    - Mass of block 2: \( m_2 \).
    - Position of block 1: \( x_1 \).
    - Position of block 2: \( x_2 \).

2. **Identify the Velocities**:
    - Velocity of block 1: \( v_{1x} \).
    - Velocity of block 2: \( v_{2x} \).

3. **Calculate the Center of Mass Velocity**:
    - The velocity of center of mass can be derived using the masses and velocities of the two blocks.

The general formula for the velocity of the center of mass (considering only motion along the x-axis) is:

### Item 6

#### Understanding Center of Mass

Understand that, for many purposes, a system can be treated as a point-like particle with its mass concentrated at the center of mass.

A complex system of objects, both point-like and extended ones, can often be treated as a **point particle**, located at the system's **center of mass**. Such an approach can greatly simplify problem solving.

---

#### Figure

The figure illustrates two masses \( m_1 \) and \( m_2 \), positioned at \( x_1 \) and \( x_2 \) on a horizontal reference line. The positions \( x_1 \) and \( x_2 \) denote the locations of the masses along the x-axis.

---
#### Part A

**Problem Statement:**

Find the \( x \) coordinate \( x_{cm} \) of the center of mass of the system.

**Instructions:**

Express your answer in terms of \( m_1 \), \( m_2 \), \( x_1 \), and \( x_2 \).

**Example of Required Answer Format:**

\[ x_{cm} = \frac{m_1 x_1 + m_2 x_2}{m_1 + m_2} \]
