In this final Saturday Explorations class students were asked to play the part of design engineers for the 'Knievel Project',
in which a toy daredevil stunt car is lauched from a track atop of a set of concrete steps, hopefully to land 'safely' on a properly placed landing pad somewhere below.
Students took measurements at the design site (the geometry of the steps), and then took
data from an experimental setting in which the car was launched from the track into a bed
of clay, where markings of distance traveled could be easily measured. The experimental
data was then used in a computer model of parabolic motion to determine initial launch
speeds and a set of design parameters (location of landing pad, geometry of launch track, starting point for the stunt car) for the actual stunt.
