sorry I have a question which I know is very ridiculous, but i really don't know where/who to ask Crying or Very sad . What is the rate of change of the rotation speed of any of Mao's jumps? (like the speed of rotation at x seconds up into the air)I need it for a calculus project. I really want to put Mao into my project lol Very Happy

There is a program called 'Dartfish' which can help you analyze a video of a skater like Mao. I know you can measure the hang time [how long a skater stays in the air], but I'm not sure you can measure the speed of rotation. I think it's a different program altogether like when the Guiness people measured the speed of the fastest spinner.

An example of Dartfish video analysis can be found here: http://www.firstpost.com/topic/person/brian-orser-samantha-cabiles-first-double-axel-combo-video-zhgRYHM7xXU-78315-4.html
