题意: 若干球最初从高到低排列,依次落下. 球与地面碰撞,速度不变方向相反,球之间碰撞, 交换速度和方向.问某一时刻各个球的高度. 分析: 把球之间的碰撞看成是擦肩而过,但是由于半径的存在,最后每个球的高度都要加上2∗i∗r,还有注意半径的单位是cm 代码: #include<cstdio> #include<cmath> #include<algorithm> using namespace std; double h[105]; int main (void) {…

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…
