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: ->->->->->->->->->->->-> :

• Sketch a straight line segment between these points.

answer/question/discussion: ->->->->->->->->->->->-> :

• What are the rise, run and slope of this segment?

answer/question/discussion: ->->->->->->->->->->->-> :

The rise is equal to 40-10 which equals 30cm/s

The run is equal to 9 – 4s which equals 5s

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

answer/question/discussion: ->->->->->->->->->->->-> :

The area of the graph is equal to (10cm/s*5s) + (½ * 5s * 30cm/s). This is equal to 50cm + 75cm which equals a total of 125cm.
