2/7 10:30I scetched the graph asked for in first and second question and then uploaded a picture to my work. When I transferred the document, the picures did not show up.
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):
Slope= 40-10 / 9-4=30/5 = 6
#$&*
Sketch a straight line segment between these points.
answer/question/discussion (start in the next line):
#$&*
What are the rise, run and slope of this segment?
answer/question/discussion (start in the next line):
rise= 40-10=30
run=9-4=5
slope=30/5=6
#$&*
What is the area of the graph beneath this segment?

@&
I believe I commented earlier on this question, in response to your question form.
Your answers here are very good and well reasoned; they lack only the necessary units. See my notes on the other document.
