Explanation:

Introduction:
- The question asks which surface will allow a toy car to travel the farthest when released with the same initial speed.
- The options given are muddy surface, cemented surface, brick surface, and polished marble surface.
- The correct answer is option 'D', which is the polished marble surface.

Factors affecting the distance traveled:
- The distance traveled by the toy car depends on several factors, such as the surface condition, friction, and the initial speed of the car.
- Friction is the force that opposes the motion of the car and affects how quickly it comes to a stop.

Friction on different surfaces:
1. Muddy surface:
- A muddy surface is generally very rough and offers a high amount of friction.
- The toy car will experience more resistance due to the mud sticking to its wheels and the roughness of the surface.
- This increased friction will reduce the distance traveled by the car.

2. Cemented surface:
- A cemented surface, such as a concrete road, is relatively smoother compared to a muddy surface.
- The friction between the car's wheels and the cemented surface will be less than that on a muddy surface.
- As a result, the car will be able to travel relatively farther on a cemented surface.

3. Brick surface:
- A brick surface is also rough, similar to a muddy surface, and offers a higher amount of friction.
- The rough texture of the bricks increases the resistance between the car's wheels and the surface.
- Therefore, the toy car will not be able to travel as far on a brick surface compared to a cemented surface.

4. Polished marble surface:
- A polished marble surface is very smooth and offers the least amount of friction among the given options.
- The wheels of the toy car will encounter minimal resistance on a polished marble surface.
- Consequently, the car will be able to travel the farthest on this surface due to the reduced friction.

Conclusion:
- The toy car will travel farthest on a polished marble surface compared to a muddy surface, cemented surface, or brick surface.
- This is because the polished marble surface offers the least amount of friction, allowing the car to maintain its initial speed and travel a greater distance.
