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):
(4cm/s + 10cm/s) / 2 = 14cm/s / 2 = 7cm/s
#$&*
• Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
because we do not know if the speed increased at a consistent rate, or if it instantly shot up to 10cm/s and rolled at that speed for a while.

• 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):
if it took three secons to go from 7cm/s to 10cm/s, then it has an average velocity of 7m/s. At this speed for three seconds the distance would be 21cm

• At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
10cm/s - 4cm/s = 6cm/s
6cm/s / 3s = 2 cm/s^2
