Description Simon ), the first ball is released and falls down due to the gravity. After that, the balls are released one by one in every second until all balls have been released. When a ball hits the ground, it will bounce back with the same speed…

物理实验 题目大意:有一个与地面垂直的管子,管口与地面相距H,管子里面有很多弹性球,从t=0时,第一个球从管口求开始下落,然后每1s就会又有球从球当前位置开始下落,球碰到地面原速返回,球与球之间相碰会发生完全弹性碰撞(各自方向改变,速率变为相碰时另一个球的速率)问最后所有球的位置? 这一题又是一道弹性碰撞模型的题目,和Liner World有点像,但是这一题不要求输出球的名字,而是要你求得各个球的高度 这道题我们只用明白一个道理就很方便了: 首先我们来看一个球的情况: 一个球从H的高度下落,碰到…
