Hi Tyler,

Does your head hurt? Did you fall to the ground?

I don't understand your question regarding the physics of the incident.

I'd be more concerned about any symptoms.

p.s. I was an athlete when young and was hit on the back of the head with a discus that swung out of the hand of a person winding up.

It was a shock. I fell to the ground. It hurt. I got back up again. I wasn't worried about the weight of the object or the speed of the object or estimating values.

Keep calm and if you have any problems you should see a doctor. It's lucky it didn't hit your eye or something. If it hit your eye it would be more worrying.
