It looks like there was an offset added to get the initial acceleration to zero - that makes it a lot harder to interpret this data. I want to see the graph with the offset taken out!
Anyway, if we had a plot of the raw data, this would be a great example of wobbling/nutation. The pumpkin seems to be spinning really fast on its axis (enough that there is more than 1g of acceleration during free-fall), but the axis that it is spinning around slowly shifts around during flight.
I am also skeptical of the scale of the second graph - was it really spinning enough to deliver 20+ g’s? And what’s with the huge acceleration after it has landed?
No public wish lists :(
