Have you ever been rock climbing and repelled down a mountain?

I've repelled down a 40 ft wall, it's required in Basic Training

39 feet!

Nope

rappelled - to go down mountain with ropes past tense
repelled - to push something away, reject it with force also past tense.
Just trying to help.

Years ago when I was in the Boy Scouts!! 🙂

Side of a building .. yes, mtn .. no
