SEED Question 2.1
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
#$&*
• Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The information needed is the time the ball was in motion.
#$&*
• 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):
3.5 cm/sec
This isn't an acceleration and you haven't shown how you got it. If I know what you were thinking I can help you correct it.

I believe I posted an identical submission. Let me know if there's a difference.
