9. A toy train moves along a straight portion of track. After two seconds of traveling at constant
velocity in the positive direction, its position is 4.0 cm. After three additional seconds of traveling at
a different constant velocity in the positive direction, its position is 5.0 cm. It travels an additional 5
seconds at yet a different constant velocity in the positive direction, its position is 10. cm. Which
time interval of the journey had the greater velocity? Justify your answer with calculations based on
the data from your graph.
