Re: [請益] 電梯突然下墜怎么辦
※ 引述《markkkkkkkk (黑崎光)》之銘言:
: 我想要問的是 如果運氣好的話
: 是不是有可能藉由往上跳停留在空中逃過一劫勒
可以這樣理解:
假設你的電梯,是從十樓(30m)的高度往下自由落體,在接近地面時,你
和地面的相對速度會接近 25ms^-1。
所以如果你要往上跳,那麼你必須讓你的速度達到向上 25ms^-1,才能變
成和地面變成 0 ms^-1。
也就是說,你必須向上跳出一個相對于電梯底部 25ms^-1的速度。
這代表什麼呢?
這代表說,如果你有這樣的腳力,你可以在平地跳到 30m 的高度,也就是
從平地一跳就跳到十樓的窗口。
除非你是美漫中的超級英雄,否則你是不會有這樣的腳力的。
