题目大意:给出k:绳子的劲度系数,l:绳长,s:桥高,w:邦德的质量,g取9.81.绳子弹力=形变量*劲度系数.如果落地速度大于10 则摔死,小于0则飘着空中. 题目思路:根据能量守恒得知:落地的动能=重力势能减少量-绳子弹力做功.如果l>s,则绳子不做功. #include<cstdio> #include<stdio.h> #include<cstdlib> #include<cmath> #include<iostream> #inc…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1155 题目很长,但是很容易理解,就是人从高s的桥上跳下来,手拉着长为l的绳子末端,如果绳子太短那么人将在空中输出Stuck in the air. 如果人落地速度大于10的话就死了,输出Killed by the impact.否则是活的输出James Bond survives. 简单的物理题:假如说人能到地上那么是重力势能转化成动能,其中会有绳子做负功: G=mgh: Wf=k*L*L/2;其中…

题意: 给你N个炮弹的发射速度,以及炮台高度H和L1,R1,L2,R2. 问任选发射角度.最多能有几个炮弹在不打入L2~R2的情况下打入L1~R1 注意:区间有可能重叠. 思路: 物理题,发现单纯的依据V去求X很困难. 这个时候想到暴力枚举角度.for(double i=0; i<=pi; i+=0.0007) 算出能到达的x.然后推断x,统计sum 发现以增长级0.0007弧度 刚刚好能过这道题 反正也是醉了~ 代码: #include"cstdlib" #include&qu…

题目链接 题意 : 刚上高一的森森为了学好物理,买了一个“非常弹”的球.虽然说是非常弹的球,其实也就是一般的弹力球而已.森森玩了一会儿弹力球后突然想到,假如他在地上用力弹球,球最远能弹到多远去呢?他不太会,你能帮他解决吗?当然为了刚学习物理的森森,我们对环境做一些简化: 假设森森是一个质点,以森森为原点设立坐标轴,则森森位于(0, 0)点. 小球质量为w/100 千克(kg),重力加速度为9.8米/秒平方(m/s2). 森森在地上用力弹球的过程可简化为球从(0, 0)点以某个森森选择的角度ang…
