## Analysis

Both the image of impact and the image after that edited together. I used the minimum distance, ie the last bit of blur of the 1^{st} image and the first bit of blur of the 2^{nd}. The ratio of the speed of the “blade” and the speed of the “stone” is 212/116, that's 1.83, which means the “stone” has almost twice the speed of the “blade”. Q.E.D.
