Transcribed Image Text: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.
