To determine which graph could represent the position vs. time for Erma's spacecraft, we would need to analyze her position over the given time period based on the data provided. However, since you did not share the actual position data points or the characteristics of each graph (W, X, Y, Z), I'm unable to assess which graph corresponds to the spacecraft's motion.
Typically, the shape of a position vs. time graph can indicate whether an object is at rest, moving at a constant speed, or accelerating.
- A horizontal line indicates the object is at rest.
- A straight diagonal line indicates the object is moving at a constant speed.
- A curve indicates the object is accelerating.
If you can provide the specific position data or describe the trends shown in the potential graphs (W, X, Y, Z), I can help you determine which one is likely the correct representation of Erma's spacecraft position over time.
