As we all now know, physics work very differently in faerun. To push someone 10-100ft only a little str is needed. Weight/mass does not go into the calculation like in our world. I guess the gods made it so as not to discriminate small and light creatures.
EVERYONE needs the shoving fun.

Also i would advise to shove your small folk, they move farther that way.

Jumping seems to be on a similay level. It was made to enable "frog-fights". Who does not want to see a bunch of heavily armoured duergar jump happily over the battlefield before hacking at you?
