The problem:
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: ->->->->->->->->->->->-> (start in the next line):
9sec
#$&*
What is the velocity at the midpoint of this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
28cm/sec
#$&*
How far do you think the object travels during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
about 252 cm
#$&*
By how much does the clock time change during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
4 sec
#$&*
By how much does velocity change during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
12cm/sec
#$&*
What is the average rate of change of velocity with respect to clock time on
this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
3cm/sec^2
#$&*
What is the rise of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
12
#$&*
What is the run of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
4
#$&*
What is the slope of the graph between these points?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
3
#$&*
What does the slope of the graph tell you about the motion of the object during
this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
it is picking up speed, the velocity is increasing
#$&*
What is the average rate of change of the object's velocity with respect to
clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
3cm/sec^2
