It is said that in ancient timjm):gg vtbe 2ukc4p(iajq00u ,yh 0 mff q*n.4es a rich man with a bag of gold coins froze to ddx s.0gd 6bx5nwl /2zreath whigx06rl b2 ws.5n/ ddxzle 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.
