The correct Answer is:
To determine on which surface the marble travels the longest distance when released from the top of the same ramp, we need to analyze the properties of each surface in terms of friction.
### Step-by-Step Solution:
1. **Identify the Surfaces**: The surfaces provided are:
- Mirror
- Sandpaper
- Wooden piece
- Plastic sheet
2. **Understand Friction**: The distance a marble travels is influenced by the friction between the marble and the surface. Higher friction will cause the marble to slow down more quickly, resulting in a shorter distance traveled.
3. **Analyze Each Surface**:
- **Mirror**: A mirror is smooth and has very low friction. This means that when the marble is released, it will experience minimal resistance and will travel a longer distance.
- **Sandpaper**: Sandpaper has a rough texture and high friction. The marble will slow down quickly and travel a shorter distance.
- **Wooden Piece**: Depending on the finish, wood can have moderate friction. The marble will travel a distance longer than on sandpaper but shorter than on a mirror.
- **Plastic Sheet**: The friction on a plastic sheet can vary, but it is generally smoother than sandpaper and wood, but not as smooth as a mirror. The distance traveled will be less than that on a mirror but more than on sandpaper.
4. **Conclusion**: Based on the analysis, the marble will travel the longest distance on the **mirror** surface because it is the smoothest and has the least friction.
### Final Answer:
The marble travels the longest distance on the **mirror** surface.

A triangular wedge A is held fixed and a block B is released on its inclined surface, from the top. Block B reaches the horizontal ground in time t. In another experiment, the wedge A was free to slide on the horizontal surface and it took t’ time for the block B to reach the ground surface after it was released from the top. Neglect friction and assume that B remains in contact with A. (a) Which time is larger t or t´? Tell by simple observation. (b) When wedge A was free to move, it was observed that it moved leftward with an acceleration (g)/(4) and one of the two measured times (t & t´) was twice the other.
