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:
the rise is `dv=30cm/s
the run is `dt=5sec
the slope(rate at which velocity changes) is the rise/run=
(30cm/s)/5sec=6cm/s^2
What is the area of the graph beneath this segment?
answer/question/discussion
`ds=avg.ht*`dt
`ds=(40cm/s+10cm/s)/2*`dt
`ds=25cm/s*5sec
`ds=125cm
