I should have clarified. I understand understand it requires somewhere in the neighborhood of 50 g's of acceleratiom to the head to cause a concussion, and I typically evaluate hits to the head by estimating their acceleration to my own head. I can't trust myself to evaluate concussions symptomatically as it get conflated with all my anxiety as of now. That's why I want to know just how fast a tennis ball would have to travel.
