It is said that in ancient times a rich man+vntau8ctli lka 9*82 with a bx3 bhpk52;3 nokp :meu+h nz2fag of gold coins froze to death whin+fhu5z kk: 2h2me3 ;bpnxpo3 le stranded on a frozen lake. Because the ice was frictionless, he could not push himself to shore. What could he have done to save himself had he not been so miserly?
参考答案: If the rich man would have faced away from the
shore and thrown the bag of coins directly away from the shore, he would have
acquired a velocity towards the shore by conservation of momentum. Since the ice is frictionless, he would slide
all the way to the shore.
