As seen below in Dragonball Z, we can see Uub jumping from one piece of rubble to the next to reach Goku in mid air. This kind of scenes are seen often in cartoons, so it made me wonder if physically speaking it would be possible to actually jump from one rock to the next as Uub did? Not sure whether this is relevant to the question, but the rocks are flying towards Goku in the pictures.
The same goes if you for example would step on a trap made out of rocks and branches put over a hole, would you be able to jump back up from the falling rubble if your reflexes are quick enough? Or would you just push the rubble down instead and fall with it?
