In movies and especially Japanese anime, you can see characters punching through walls, breaking columns by kicking etc. Similar effect is seen in computer games, which is something I'm interested in at the moment.
It seems to me that many of these destructive effects require more energy than how much energy is needed to throw you flying. In other words, if you have nothing to brace against, you maybe just push yourself away from the target object very fast, without harming it much.
And the question is quite simple:
- Given you're strong enough (and your tissues are tough enough, magically) to break a marble column or punch through car roof, are you able to do that at normal weight (say, 80kg)?
If answer is no, then what exactly happens? Do you push yourself meters in the air? What happens after two super-persons lock their swords (magical, indestructible) with that force in a typical anime sword-fight? Do they fly apart at supersonic speeds?
It would be nice to have some basic math leads to the results. Pointers are enough, as this is not Physics.SE question.
This is also not duplicate of the question mentioned in comments, because the other question asks about effects on target human body, while this one considers all humans involved indestructible.
