To solve this problem, let's go through each step in analyzing the forces involved. Here’s a breakdown of the setup based on the image:

### Problem Breakdown:
- There is a system of masses connected by ropes and pulleys.
- Masses given:
  - Block on the table: \( m = 2.6 \, \text{kg} \)
  - Block hanging off the side: \( m_1 = 1.0 \, \text{kg} \)
  - Block hanging on the other side: \( m_2 = 3.0 \, \text{kg} \)
- Coefficient of kinetic friction (\( \mu_k \)) between the 2.6 kg block and the table: \( 0.22 \).
- We are asked to find the acceleration of the 2.6 kg block.

### Solution:
1. **Identify Forces on Each Block:**

   For the 2.6 kg block on the table:
   - **Tension (T1)** from the rope connected to the 1.0 kg mass (left side).
   - **Tension (T2)** from the rope connected to the 3.0 kg mass (right side).
   - **Frictional Force (f)**: \( f = \mu_k \cdot N \), where \( N \) is the normal force. Since the block is on a horizontal table, \( N = m \cdot g = 2.6 \cdot 9.8 = 25.48 \, \text{N} \).
     So, \( f = 0.22 \cdot 25.48 = 5.6056 \, \text{N} \).

2. **Equations of Motion for Each Mass:**

   For the 1.0 kg mass (left side, hanging):
   - The only forces acting are the gravitational force and the tension \( T1 \).
   - Equation: \( m_1 g - T1 = m_1 a \).

   For the 3.0 kg mass (right side, hanging):
   - The only forces acting are the gravitational force and the tension \( T2 \).
   - Equation: \( T2 - m_2 g = m_2 a \).

   For the 2.6 kg mass (block on the table):
   - The net force is due to the difference in tensions, minus the frictional force.
   - Equation: \( T2 - T1 - f = m a \).

3. **Set Up System of Equations:**
   
   Substitute known values:
   - \( m_1 = 1.0 \, \text{kg} \)
   - \( m_2 = 3.0 \, \text{kg} \)
   - \( m = 2.6 \, \text{kg} \)
   - \( g = 9.8 \, \text{m/s}^2 \)
   - \( f = 5.6056 \, \text{N} \)

   Using the three equations, we can solve for \( a \).

### Follow-Up Questions:
1. What if the coefficient of friction were different? How would the acceleration change?
2. How does the mass of each block affect the system's acceleration?
3. If one of the masses is removed, what would the resulting acceleration be?
4. What role does tension play in the forces acting on each block?
5. How would the scenario change if there were an additional block on the table?

### Tip:
For systems of connected masses, breaking down the forces acting on each individual mass can simplify the solution.

The coefficient of kinetic friction between the 2.6 kg block in the figure below and the table is 0.22. What is the acceleration of the 2.6 kg block?
