It is said that in ancient times a rich man with a bag of gold coins was stranded on the surface of a frozen lake. because the ice was frictionless, he could not push himself to shore and froze to death. what could he have done to save himself had he not been so miserly?

If the rich man had not been so miserly, he would have understood the concept of momentum and velocity. All he needed at that point was momentum to acquire a certain velocity. All he would have done was to face away from the shores and throw the bag of coin with great force. This way, he would have acquired the velocity needed to push him to the shore by conserving some momentum. After all it is stated in the question that the ice is frictionless and thus he would be able to slide down to the shore.
