Based on the given information in Model 1, the answers to the questions are as follows:

1. Which skateboarders are located at the starting line at Stopwatch Time = 0?
- Answer: Both skateboarders (c).

2. Highlight skateboard A in one color wherever you see it in Model 1. Highlight skateboard B in a different color.
- Answer: We cannot physically highlight the skateboarders, but we can identify Skateboarder A as the one on the left, and Skateboarder B as the one on the right.

3. Look carefully at the positions of the two skateboarders as time passes. Circle the direction that the skateboarders are moving.
- Answer: Skateboarder A is moving to the left, while Skateboarder B is moving to the right.
