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).
answer/question/discussion: ->->->->->->->->->->->-> : Between these two points the graph forms a straight line.
• Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> :
• What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> :
Rise = 40 – 10 = 30
Run = 9 – 4 = 5
Slope = 30 cm/sec / 5 sec
Slope = 6 cm

• What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> :
Area = ½ (30/5)
Area = ½ (6)
Area = 3 cm
