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: ->->->->->->->->->->->-> scussion (start in the next line):
(10cm/sec+4cm/sec)/2 = 14/2= 7cm/sec
#$&*
*
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> scussion (start in the next line):
I need to know the time it took the object to go from 4cm/sec to 6cm/sec
#$&*
*
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: ->->->->->->->->->->->-> scussion (start in the next line):
7x3= 21cm traveled
#$&*
*
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> scussion (start in the next line):
(10cm/sec-4cm/sec)/3seconds= 6/3= 2cm/sec/sec
