  • Online:2011-02-25 Published:2011-02-20

Abstract: A misunderstanding for a cord being lifted up or falling down is analyzed, there is a point of sudden change of velocity in it. A way to solve the problem is proposed and which is examined by experiment.

Key words: soft-cord problem, momentum theorem, energy theorem, trap
