10 m forwardSteepest Positive Slope10 m back20 m forward At a soccer practice, the players run sprints. Theystart at the goal, run 10 m toward the center of thefield and then run back to the goal. Then they run20 m toward the center of the field and back to thegoal. Finally they run 30 m toward the center of thefield, turn around, and run back to the goal again.One player times herself to try and beat herpersonal best time. She runs the first 10 m in 2.5 sand gets back to the goal in 2.8 s. Then she runsthe 20-m sprint in 5.7 s and gets back to the goalin 6.7 s. She runs the final 30-m sprint in 12 s andgets back to the goal in 15 s.Define the positive direction as forward, towardthe center of the field and consider what aposition versus time graph of her motion wouldlook like. Rank the sprints according to theirslopes on the position versus time graph, fromsteepest positive slope to steepest negative slope.Rank from steepest positive slope to steepestnegative slope. To rank items as equivalent,overlap them.
