Talk:Puzzles/How do you ... ?/Crossing the Bridge/Solution

The solution in my opinion is not correct. Even though during the juggling process, one of the apples is in the air, if you consider the man+ 3 apples as a system, this system is applying an average force of 101kg on the bridge. (actually, while throwing the apple up in the air, you exert a very large impulsive force and then you go back to your man + 2 apples weight)

I believe the solution is incorrect.
