题意: 有个人在蹦极,给出悬崖的高度,绳子的长度,弹簧绳的胡克系数 以及 人的质量. 判断人是否能够着地,能的话是否能安全着地.所谓安全着地就是到达地面的速度不超过10m/s. 分析: 学过一点高中物理的就应该能解出来吧,既然是题解还是本着详细具体的原则来写. 首先要求人能下落的最大高度,也就是重力做的功全部转化为弹簧绳的弹性势能. ,解出Δl: 那么人能下落的最大高度就是l + Δl 如果人能落地,还要看绳长l与悬崖高度s的关系 l>=s,则重力做的功全部转换为动能,,解得 l<s,重力做的…

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…

HDU 1087 题目大意:给定一个序列,只能走比当前位置大的位置,不可回头,求能得到的和的最大值.(其实就是求最大上升(可不连续)子序列和) 解题思路:可以定义状态dp[i]表示以a[i]为结尾的上升子序列的和的最大值,那么便可以得到状态转移方程 dp[i] = max(dp[i], dp[j]+a[i]), 其中a[j]<a[i]且j<i; 另外每个dp[i]可以先初始化为a[i] 理解:以a[i]为结尾的上升子序列可以由前面比a[i]小的某个序列加上a[i]来取得,故此有dp[j]+a[…
