**Problem 18: Physics - Mechanics**

An object with mass \( M_1 = 8 \, \text{kg} \) rests on a frictionless horizontal table. It is connected by a cable that passes over a pulley and is then fastened to a hanging object with mass \( M_2 = 12 \, \text{kg} \). As shown in the figure, find the acceleration of each object and the tension in the cable. 

**Answer:**
- Acceleration \( a = 5.88 \, \text{m/s}^2 \)
- Tension \( T = 47.1 \, \text{N} \)

**Diagram Explanation:**

The diagram accompanying this problem depicts a horizontal table with object \( M_1 \) on it, connected by a cable to a pulley at the edge of the table. The cable hangs vertically over the side of the table, attached to object \( M_2 \), which hangs freely. The setup illustrates a typical pulley system used to analyze forces and motion in physics.

The cable hangs vertically over the side of the table, attached to object \( M_2 \), which hangs freely. The setup illustrates a typical pulley system used to analyze forces and motion in physics.
**Problem Statement:**

An object with mass \( M_1 = 2 \, \text{kg} \) rests on a rough horizontal table. The coefficient of kinetic friction is 0.25 between the block and the table. This object is connected by a string that passes over a pulley and is fastened to a hanging object with mass \( M_2 = 4 \, \text{kg} \). As shown in the figure, (a) find the acceleration of each object and (b) the tension in the cable.

**Diagram Description:**

The diagram illustrates a pulley system. 

- A block labeled \( M_1 \) (mass 2 kg) is positioned on a horizontal surface to the left of a pulley.
- The surface is noted as being rough, implying the presence of friction.
- A string connects \( M_1 \) over the pulley to another block labeled \( M_2 \) (mass 4 kg), which hangs vertically.

**Note:** The force of friction, the tension in the string, the gravitational forces on the blocks, and the direction of acceleration should be considered to solve the problem.
