Transcribed Image Text:The image depicts a block leaving a frictionless inclined surface horizontally. The block initially starts at a height \( h \) with zero velocity (\( v = 0 \)) and then transitions to a lower surface from a height \( H \), moving horizontally with velocity \( v \).
Key components:
- **Initial Configuration**: The block is at a height \( h \) above the ground, where \( v = 0 \).
- **Inclined Surface**: The inclined plane allows the block to slide down without any friction.
- **Horizontal Launch**: After descending, the block moves off the edge horizontally at a certain velocity \( v \).
- **Vertical Drop**: The block falls a vertical distance \( H \) to the floor beneath.
- **Horizontal Displacement**: The block covers a horizontal distance \( D \) from the edge to the point it lands on the floor.
Given values:
- \( h = 4.4 \, \text{m} \)
- \( H = 2.2 \, \text{m} \)
The task is to find the horizontal distance \( D \) where the block will land.
At the bottom, there is a box labeled "D = ___ m" for entering the calculated distance \( D \).
