At a soccer practice, the players run sprints. They start at the goal, run

10m

toward the center of the field and then run back to the goal. Then they run

20m

toward the center of the field and back to the goal. Finally they run

30m

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

.\ 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.
