Which "Headline" best describes a possible real world situation illustrated by this position vs time graph?

• The runner ran forward for 2 seconds, and then backward for 2 seconds.

• The runner ran forward for 2 seconds, and then stood still for 2 seconds.

• The runner ran forward for 2 seconds, and then ran forward more slowly for 2 seconds.

• The runner ran uphill slowly for 2 seconds and then sped up for 2 seconds.

Which of the following best describes the motion of Red Runner and Blue Runner at the intersection on the pictured position-time graph?

• Red Runner and Blue Runner have the same velocity when the lines intersect.

• Red Runner and Blue Runner are moving at the same speed when the lines intersect.

• Red Runner is taking the lead ahead of Blue Runner in the race.

• Red Runner and Blue Runner are intersecting.

• Red Runner and Blue Runner are passing each other going opposite directions.

At what point do both objects have the same speed? Explain why.

• At 0 seconds both objects have the same speed because they just started moving.

• At 4 seconds both objects have the same speed because the graph stops at 4 seconds.

• At 1 second both objects have the same speed because they're at the same place.

• The objects don't have the same speed at any point because the slopes of the lines are always different.
