Question

On the top graph is a diagram of a water slide.  A person starts at rest at the top of the slide.  Her mass is 60 kg.  (1ft = 0.305 m)

Neglecting friction, what is her speed at the end of the slide?

Neglecting friction, what is her speed when she is at the 40 ft mark on the horizontal axis?

If her final speed at the end of the slide was actually 18 m/s, how much work was done by friction on the person?

The image depicts a graph showing the relationship between horizontal distance (in feet) and height (in feet). The graph is plotted on a grid, with the horizontal distance ranging from 0 to 100 feet and the height ranging from 0 to 100 feet.

### Description of the Graph

- **X-axis:** Represents the horizontal distance, marked at intervals of 5 feet, spanning from 0 to 100 feet.
- **Y-axis:** Represents the height, marked at intervals of 10 feet, spanning from 0 to 100 feet.

### Graph Characteristics

1. **Curve Shape:** 
   - The curve begins at a height of 100 feet at the 0 feet mark on the horizontal distance.
   - It initially descends to around 70 feet as the horizontal distance reaches approximately 20 feet.
   - The curve then rises slightly, reaching around 80 feet at the 30-foot mark.
   - A gradual decline occurs, reaching approximately 55 feet at the 50-foot mark.
   - The descent continues, reaching its lowest point, around 5 feet, near the 85-foot mark.
   - Finally, the curve rises slightly towards the end of the graph.

### Interpretation

This graph could be interpreted as representing the trajectory of a projectile, such as a ball thrown across a field, showing how the height of the projectile changes over the horizontal distance it covers.
