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):
v_avg = (10cm/sec + 4cm/sec) * 0.5 = 7cm/sec
#$&*
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Because more information is needed to be accurate.
#$&*
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):
21cm (multiply 'ddistance by 'dvelocity)
#$&*
At what average rate did its velocity change with respect to clock time during
this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
2cm / sec^2
#$&*

10 minutes
