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: ->->->->->->->->->->->-> :
Rise = 40cm/s – 10cm/s = 30cm/s
Run = 9s-4s = 5s
Slope = (30cm/s) / 5s = 6cm/s^2
• What is the area of the graph beneath this segment?
answer/question/discussion: ->->->->->->->->->->->-> :
The area represents the change in position.
