枫下沙龙 / 休闲娱乐 / 中学的时候有一道考试题，我到现在还不知道答案，也不知道为什么，现在贴出来给大家娱乐娱乐，给我传道授业解惑，谢谢。一根木头飘在河里，请问：是河里的水先流到下游，还是木头先到?也就是说，水和木头，谁快？

一条河中每一个点的流速都不一样， 怎么算？

现在考这些高材生，你就更得不出答案来了。往简单处考虑，一样吧。木头受3个力，重力，浮力和摩擦力和阻力。摩擦力推动木头向前，就跟人推着车子一样了么。人先到还是车子先到？

这个问题应该按流体力学来考虑,只有在平流的情况下,水中各质点的速度才是一样的,而平流是理想情况.

我觉得,如果是平流的情况下,(河床绝对平坦,均匀,成直线),应该一起到.如果不是的话,就看和那里的水一起到了.

water or wood which one come first depends on the slope of the river.

速度<>加速度。木头不可能一直加速。当木头加速度为0的时候，摩擦力被前面的水的阻力抵消，你说谁先到？

应该这样说，把一块木头放在车上，车拉着木头向走，谁先到。
