The problem:
A ball starts with velocity 4 cm/sec and ends with a velocity of 10 cm/sec.
What is your best guess about the ball's average velocity?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
7 cm/ sec
#$&*
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Because in a guess, calculations are typically not performed
#$&*
@&
Your 'best guess' could, and probably did, involve calculations.

If it takes 3 seconds to get from the first velocity to the second, then what is your best guess about how far it traveled during that time?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
21 cm
#$&*
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
2 cm/sec
#$&*

This is not correct, and will need to be revised. Be sure to include a complete explanation, starting with how you applied the definition of average rate of change to this situation.

@&
Good for the most part, but you do need to include at least a brief explanation of how your results were obtained.
Your answer on that last question does need to be revised.
