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?

**40cm/s-10cm/s=30cm/s

**9s-4s=5s

**30/5=6
