If Velvet had the guts to kick Cardin's ass herself, she would have simply ripped-off Yatsuhachi. Then again, it's possible her weapon wasn't finished so the best she could do is kick and punch.....with which she could've still beat their asses.

Overall, the only reason Velvet didn't kick Cardin's ass is because she had no guts to do so.

Phantom already explained the reason why the teachers do nothing. As for why Ruby and co. did nothing, they barely knew Velvet back then. Then again, they barely did anything for Jaune either.
