Define the positive direction as forward, toward the center of the field and consider what a position versus time graph of her motion would look like. Rank the sprints according to their slopes on the position versus time graph, from steepest positive slope to steepest negative slope.

10 m forward Steepest Positive Slope 10 m back 20 m forward
Transcribed Image Text:10 m forward Steepest Positive Slope 10 m back 20 m forward
At a soccer practice, the players run sprints. They start at the goal, run 10 m toward the center of the field and then run back to the goal. Then they run 20 m toward the center of the field and back to the goal. Finally they run 30 m toward the center of the field, turn around, and run back to the goal again. One player times herself to try and beat her personal best time. She runs the first 10 m in 2.5 s and gets back to the goal in 2.8 s. Then she runs the 20-m sprint in 5.7 s and gets back to the goal in 6.7 s. She runs the final 30-m sprint in 12 s and gets back to the goal in 15 s. Define the positive direction as forward, toward the center of the field and consider what a position versus time graph of her motion would look like. Rank the sprints according to their slopes on the position versus time graph, from steepest positive slope to steepest negative slope. Rank from steepest positive slope to steepest negative slope. To rank items as equivalent, overlap them.
