[问答题]
It is said that in ancient tj l upe69)f iq1;mpa9ii0/g7e* yj.ur neqic/ imes a rich man ios5*v*b2f tz;b/mm k with a bag of gold coins froze to death while stranded on a frozen lake. Because the ice was frictionless, he could not push hims *t*mis2ozb/ f5vkbm; elf 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.
