Have you seen Superman III and if so...

[Wayne]

Think about it: Superman could hock a loogie and blow a hole through you with it. He could thump you to death. He could kiss your cheek and rip half your face off.

never understood superman II when the others from his world hit him he flew a mile & vice versa anyone help here

I think it's supposed to be if they weren't prepared for the punch. If they had punched a human like that it would have just ripped a hole in him, but that force just blew them back. Think of it like kicking a rubber ball. Your foot isn't strong enough to tear it in half, but you can kick it hard enough to send it pretty far.
