The jogger could NOT use a car in motion to determine her motion. Here's why:
1. A car in motion is not a stationary reference point for the jogger. The jogger needs fixed objects like trees, houses, or telephone poles to determine her own motion relative to those stationary objects.
2. When the jogger passes a tree, house, or telephone pole, she can visually track her movement based on how these stationary objects appear to move relative to her position.
3. In contrast, a car in motion would not provide a reliable reference point for the jogger because the car is also moving, making it difficult for her to gauge her own motion accurately based on the car's movement.
In conclusion, while a car in motion may be moving parallel to the jogger, it is not a suitable reference point for determining her own motion due to its dynamic nature.
