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: ->->->->->->->->->->->-> I would guess that the average velocity would be 7 cm/sec. I would guess this because I took the initial velocity and added it to the final velocity and then took ½ of that. I did this all mentally because it was simple enough to do the math in my head and guess it.
Without further information, why is this just a guess?
Answer: ->->->->->->->->->->->-> This is just a guess because I am guessing that this is the right way to find out the average velocity. I remember from high school that the equation was something like that but I wanted to still guess and see if I am right.
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: ->->->->->->->->->->->-> I would say it traveled around 20 cm. This is because it could have taken some time to build up to the speed and not a constant speed and I said 7 cm/sec was the average so I guessed just a little shy of if it was at 7cm/sec the whole time.
At what average rate did its velocity change with respect to clock time during this interval?
Answer: ->->->->->->->->->->->-> the rate I would guess was a 3 to 1 ratio as in every second the average velocity raised 3 cm/sec.
