武汉5月供题第10题解法分享v-I图(5)

该题是武汉五月的一个习题，答案不难，对于位移即是一个一个写也是没多少时间，但写的时候要去分那些字母角标，我放弃逐推，直接上图像，本打算上周四分享的，但遇到了好玩的习题，他就推迟了

题目如下

如图所示，在水平面上相距足够远处静置着两个质量均为的物块、，在、之间有一质量为的光滑物块。现给水平向右的初速度。已知、与地面间的动摩擦因数均为，重力加速度大小为，所有碰撞均为弹性正碰。下列说法正确的是(     )

A．与第一次碰撞后瞬间，二者速度大小相等

B．与第二次碰撞前，的位移大小为

C．的总位移大小为

D．的总位移大小为

解析 多次相碰必定要写数列，懂的都懂！不想写咋办，来画图

武汉之后,下一个靠大学城留住年轻人完成人才积累的城市,可能是成都

必须承认:武汉,才是湖北最不适合被定义的“小而美”城市
