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:
I would give the average velocity as 7 cm/sec
Without further information, why is this just a guess?
answer/question/discussion:
The velocity could have accelerated to a velocity greater than 10 cm/sec, but then reduced velocity to 10 cm/sec at the end.
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:
21 cm
At what average rate did its velocity change with respect to clock time during this interval?
answer/question/discussion:
2 cm/sec^2 acceleration
** **
20 minutes
