This video will give you some quick instructions on how to find the average velocity on a "physlet." Here is a helpful tip, for a constantly accelerating body, the average velocity is the instantaneous velocity at the mid point in the TIME interval. (Not the mid point in the distance interval.) So if you found the average velocity to be 4 m/s between 6 and 10 seconds, then the instantaneous velocity is exactly 4 m/s at 8 seconds.
