Punching Rollerblader
Question: If a 168 pound runner moving at 5:30/pace throws a haymaker at a rollerbladder coming towards him at the same speed, what will the force exerted on this guy's face be?

I want to cross paths with him so badly tonight.

Ah physics. If I remember correctly ( and I probably don't) Force or Kinetic Energy is Half Mass times Velocity Squared. I think.

That's the equivalent of 500kg sitting on his face. In ~6-7sq inches. So 155-180psi. It takes 160 to break bone.
You can do it, Dave!
