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): (4cm/s+10cm/s)/2=
7cm/s
#$&*
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line): The problem does not tell if the hill is only downhill or if there is a possibility of different slopes.

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): 7cm/s*3s=
21cm
#$&*
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line): 10cm/s-4cm/s=Gain of 6cm/s
(6cm/s)/3s=
2cm/s/s
