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: **************** 7cm/sec
• Without further information, why is this just a guess?
answer/question/discussion: **************** You cannot accurately predict the actual velocity, this is just an average.
• 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: **************** 12 cm
• At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: **************** 6cm/sec
** **
10 minutes
