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):
7cm/sec
#$&*
Without further information, why is this just a guess?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
This is a best guess becuase if you had the change in time, rather than two velocities, you
could get a better result.
#$&*
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):
21cm based on the guess that the average velocity it 7cm/sec.
#$&*
At what average rate did its velocity change with respect to clock time during this
interval?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
Do we have enough information to calculate this? It seems we need another time?
#$&*
@& You want to find the average rate of change of velocity with respect to clock time.
What is the definition of average rate of change of A with respect to B?
How does that apply to this question?
What information do you have in the problem that gives you the necessary quantities?
Don't let yourself get tied up on these questions. Give yourself 10 minutes and give me your best answer. I expect you're likely to get it, but if not we'll go from there.*@
