Parametric Curves, Part 22 (Modeling the trajectory of a ball, Part 1)

Modeling the trajectory of a ball, Part 1. Key facts emphasized: the velocity vector is the derivative of the position vector, the speed is the norm (length) of the velocity vector, and the distance traveled can be found via integration of the speed function. The videos that came before this one have set the stage by focusing on the main ideas with a simple example. From this point, we can more quickly work through harder examples. Details of some Mathematica code from previous videos is also reviewed in this video.
