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?
7cm/sec would be my best guess because it is the average of the two rates.
Without further information, why is this just a guess?
This is just a guess because I don’t know the slope of the incline to be constant.
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?
I would use the average and say that it is 21cm traveled in three seconds.
At what average rate did its velocity change with respect to clock time during this interval?
2cm/sec : 1sec or 2 cm/sec/sec that is because it is 6 divided by three that is equal to two.
