Why are the engines of a supertanker normally cut off 25 km from port?
我知道是因为万吨轮惯性很大，但是需要25公里才能停下来？？水的阻力应该也很大啊……盼高人指点，低人一边去少来骚扰。
这是新加坡物理教材上的思考……专业度还是靠得住的，应该不会有错

The key points you should pay attition on is the question itself !
Cause your comprehension of the sentence is uncorrect.

The supertanker normally cut off 25km from port in order to avoid accidents for its large inertia.It doesn't means that the displacement the supertanker needs to cut off itself is about 25km .

谁说的.
这个结论本来就是错误.

我还记得有部电影,万吨邮轮,几百米就可以停下来. 发动机可以反向运转.类似汽车的倒车,飞机发动机的反喷

水的阻力大，可是你也说了，惯性很大啊，就这个原理嘞
