You and your friends find a rope that hangs down 15 m from a high tree branch right at the edge of a wide river. You find that you can run, grab the rope, and swing out over the river. You run at 2.0 m/s and grab the rope, launching yourself out over the river. How long must you hang on if you want to stay dry?
