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):
I was unclear on how to sketch the graph on the computer. Therefore I am writing what I did. The y axis represents the velocity and the x axis represents the time. The y axis is labeled 10-14 in increments of ten and the x axis is labeled 1-9 in increments of 1. I put the two points on the graph that were indicated in the question.
Sketch on paper. Describe on the computer, as you did.

• Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
I drew a straight line between these points.

• What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The rise is the change in velocity which is 30 cm/sec. and the run is the change in tim which is 5 seconds. The slope is 6.
the slope has units

• What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
There is not a lot of area towards the beginning of the line but as the numbers increase and the graph increases, the amount of area beneath the line gets to be greater.

That area can be calculated. That's probably the only thing that needs revision, but you should submit at least that much.
