The problem:vvvv
A graph is constructed representing velocity vs. clock time for the interval between clock times t = 5 seconds and t = 13 seconds. The graph consists of a straight line from the point (5 sec, 16 cm/s) to the point (13 sec, 40 cm/s).
• What is the clock time at the midpoint of this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 9 seconds
• What is the velocity at the midpoint of this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 28 cm/s
• How far do you think the object travels during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 25.3 cm
• By how much does the clock time change during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 8 seconds
• By how much does velocity change during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 24 cm/sec
• What is the average rate of change of velocity with respect to clock time on this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 3 cm/s
• What is the rise of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> : 24 units
• What is the run of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> : 8 seconds
• What is the slope of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> : 3
• What does the slope of the graph tell you about the motion of the object during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : The velocity is increasing by a rate of 3 cm/s.
• What is the average rate of change of the object's velocity with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 3cm/s
