The cart moves 93cm when the string moves 43cm, the cart is 2.16 times as fast as the string, exclamation point, QED, more exclamation points.
Thanks. I could see the video portion, but no audio.
Can you provide a transcript of what the presenter was saying?
------------------------------------------------------------------------------------
1) Did you notice that the pull-string shortens during the presentation.
2) The string is being wound around a spool within the 'cart'.
3) If there is a spring-powered clock-drive, or battery-powered- motor-spool within the 'cart', this power , added to the 'system', is what's responsible for the phenomena you are experiencing, as the string continuously winds itself onto the spool.
4) A parlor trick.
5) A visual distraction from the actual dynamics.
