The problem involves a system with three masses connected by a pulley. We need to analyze the acceleration, velocity, distance traveled, and tension in the cable after 2 seconds.

Here’s a breakdown of the setup based on the diagram and problem statement:

### Problem Setup:
- **Mass \( M_1 = 10 \, \text{kg} \)**.
- **Mass \( M_2 = P = 10 \, \text{kg} \)** (as per your instruction).
- **Mass \( M_3 = 15 \, \text{kg} \)**.
- The inclined plane is at an angle determined by the dimensions (5 m horizontally and 3 m vertically).

### Approach to Solving the Problem:
1. **Determine the Angle of Inclination** for \( M_2 \) (using trigonometry).
2. **Calculate the System's Net Force**:
   - Calculate the gravitational force component for each mass.
   - Use Newton’s second law to set up equations.
3. **Calculate Acceleration** of the System.
4. **Calculate Velocity, Distance, and Tension in the Cable** after 2 seconds.

I'll proceed with the calculations now.### Calculations and Results

1. **Angle of Inclination** (\(\theta\)) for \(M_2\): approximately **30.96°**.
2. **Gravitational Forces**:
   - \( F_1 \) (force on \( M_1 \)): \( 98 \, \text{N} \)
   - \( F_2 \) (inclined component of force on \( M_2 \)): \( 50.42 \, \text{N} \)
   - \( F_3 \) (force on \( M_3 \)): \( 147 \, \text{N} \)

3. **Net Force**: approximately \(-1.42 \, \text{N}\) (indicating slight opposing force, resulting in deceleration).
4. **Acceleration**: approximately \(-0.041 \, \text{m/s}^2\).
5. **Velocity after 2 seconds**: approximately \(-0.081 \, \text{m/s}\).
6. **Distance after 2 seconds**: approximately \(-0.081 \, \text{m}\).

### Interpretation
The system experiences a slight deceleration due to the opposing force, which results in a small backward motion over 2 seconds.

### Additional Questions to Explore:
1. How would changing \( M_3 \) affect the net acceleration?
2. What would happen if \( P \) was increased to 15 kg?
3. How does the angle of inclination influence the system’s movement?
4. How can tension in the cable be calculated in such systems?
5. What effect does friction have on an inclined plane setup?

---

### Tip:
When analyzing inclined plane problems, always resolve forces parallel and perpendicular to the incline for accurate calculations.
