The problem:
A ball is moving at 10 cm/s when clock time is 4 seconds, and at 40 cm/s when clock time is 9 seconds.
• Sketch a v vs. t graph and represent these two events by the points (4 sec, 10 cm/s) and (9 s, 40 cm/s).

• Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
#$&*
• What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The rise is 9 sec – 4 sec = 5 sec, the run is 40 cm/s – 10 cm/s = 30 cm/s thus the slope is (30 cm/s) / (5sec) = 6 cm/sec2

• What is the area of the graph beneath this segment?
