So i'm in a d&d campaign, and my character is in a situation where he is holding a rope about 10 feet from the ledge of a 20 foot pit. The pit is 10 feet across. My fellow adventurers are on the other side and I offered to hold onto this 20 foot rope as they attempt to jump across like I did. If they failed, I would be in an already ready position to start pulling them up from their fall. Sadly, the 1st jump whiffed hardcore and the DM i fell attempting to pull him up.
Here are the numbers: My weight 140 kg,
6'5" for height,
rope is considered waist level,
i'm supposively standing 60 degrees relative to the ground
(leaning back),
basically dirt for friction purposes
His weight, 90 kg,
was in free fall for 1 second i guess? the acceleration due to gravity is same as earth's.

So, the question is, did I fail to wistand the force and fell in, or did I pull him up?
