4.中国探月工程公布信息,“嫦六号"计划在2024年进行发射,前往月球背面采集样品,实现人类历历史上首次月背采样返回。设想“嫦娥六号”抵达月球周围被月球捕获后先做椭圆运动,在合适位置调姿、变轨、着陆,然后开始探测任务。已知月球质量为m、、半径为,近月点M与月球表面的距离为,远月N与月球表面的距离为Hn运动轨迹如图所示,以下说法正确的是()A.“嫦娥六号”通过近月点时速率等TGmR+hB.“嫦娥六号”在近月点和远月点的速率之比为R+1R+1C.“嫦娥六号”在近月点和远月点的加速度大小之比(R+h)^2(R+H)^2D.“嫦娥六号"着陆月球背面过程要失重

(3)某小组在实验中打出纸带的一部分如图乙所示,用毫米刻度尺测量并在纸带上标出了部分计数点的间距.已知打点计时器使用的低压交流电源的频率为50Hz..由图乙中数据可求得打点计时器打下A点时,小车的瞬时速度大小为m/s;小车做匀加速直线运动的加速度大小为m/s^2.(计算结果均保留三位有效数字
