The first thing came to my head when I saw the kinetics assignment was physics class at high school, something like "find the final kinetic energy of the train if it started from rest..."
Well today I don't have to deal with this horror anymore (until my children will be at high school).
I took out my children "choo choo" train, set the flash to fire at the 2nd-curtain sync and fire.
This is what I got.
