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: ->->->->->->->->->->->-> (start in the next line):
The velocity would go up the y axis and the time would go down the x axis.
The slope of the graph would be increases and the graph would be increasing

• Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
the straight line segment would go upward and to the right
#$&*
• What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The rise would be 30cm/sec
The run would be 5sec
The slope would be 6cm/sec/sec

• What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Finding the area of a graph is something that I have not done before, or if I have I do not remember. Would one use the area formula to accomplish this task????
The region is a trapezoid. You went over this in the Orientation exercise on areas. However the link at the end will refresh you.
