I originally asked this in worldbuilding due to the context, though I suppose it's just a physics question.
I was never great at physics in school but let's say there's a super human and they're flying at around 450 km/h and they weigh around 95 kg. They have their fist stretched out in front of them. How much force is behind this fist? If it punched someone how much weight would it feel like if that's how it works? I know impact time has something to do with it all but I'm not quite sure what.
I used some online calculator and got 742188 Joules but I'm not quite sure what this means, to be honest. (I know now this is regarding energy and not force or momentum).
For simplicity's sake let's say the target is a pillar that is stationary and not fixed to the ground. It's 2m tall and weighs 100kg while the hero is flying parallel to the ground.
