A FreeFall Problem That You Must Split Into Two Parts
Flipping Physics posted a video in Kinematics
This is a complicated freefall problem where you have to identify that the velocity at the top of the path is zero in the ydireciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem into two different parts. A classic freefall acceleration example problem.

In this introductory freefall acceleration problem we analyze a video of a medicine ball being dropped to determine the final velocity and the time in freefall. Included are three common mistakes students make. "Why include mistakes?" you might ask. Well, it is important to understand what happens when you make mistakes so that you can recognize them in the future. There is also brief description of "parallax" and how it affects what you see in the video compared to reality.

This video starts with a simple acceleration problem and then addresses a commonly held misconception that a negative acceleration always means you are slowing down. I do this by way of examples. Kate (my wife) drove the Prius with a camera suction cupped to the window and videoed me riding my bike several times. In the end I ended up with four different examples on the screen at once and 25 different video layers to describe it all. I am really proud about how well it worked. Enjoy.
