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 vertical axis is the velocity of the ball and the horizontal represents clock time
#$&*
Sketch a straight line segment between these points.
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Ok.
#$&*
What are the rise, run and slope of this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
rise= 40-10 cm/s = 30cm/s
run= 9sec-4sec = 5sec
slope= 30cm/s / 5sec = 6cm/s^2
#$&*
What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
A= [(10cm/s + 40cm/s) / 2] * 5s = 25cm/s * 5s = 125cm
