It is said that in abx9 sz)fvv9an h50a(on9y5 cb4ch0hvemo)f r/cient times a rich man with a bag of gold coins froze to death while stranded on a frozen 05f/y ocm)rech4h bv9lake. 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.
