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: ->->->->->->->->->->->-> : My guess about the ball’s average velocity would be to take the average of 4 cm/s and 10 cm/s, which would be 7 cm/s.
Good.
• Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> : This is just a guess because there isn’t much information to go by.
• 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: ->->->->->->->->->->->-> : My best guess would be to use the average velocity I guessed of 7cm/s and multiply it by the time of 3 seconds. This would give a distance traveled of 21 cm.
Good.
• At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> : 2.3 cm/s^2. This was obtained by taking the average velocity of 7 cm/s and dividing it by the time interval of 3 seconds.
this needs to be corrected
