关于MATLAB编程问题

一个自由长度为L0的弹簧，一段固定于原点，另一端栓有质量为m的物体，整个系统放在水平桌面上，设初始时刻，将弹簧拉长到L，同时给物体一个垂直于弹簧的初速度V0，则物块将围绕原点转动，忽略弹簧质量和物体大小后，上述过程称为二维谐振子，请编写程序研究不同初始条件下物块的运动轨迹。大家各显神通，帮帮忙啊！

问题补充，请用matlab,帮我编译吧，然后能解释下吗

懂matlab，但真心不懂运动的公式

有人能解决不，在线等

这个是百度问答，希望能帮助你帮助我解决

之后可以追加 再给金币的

Essentially that is sort of number theory problem, i.e.
With certain condition between the spring constant and the initial speed, the ball will just cover the same line over and over again on each circle (when 2* \pi * L0 / v happends to be integer time of the period of spring)
However, with other condition, the ball might cover different trace at different circle, thus will cover part of the circle of radius L (could it possibly to be all? maybe not due to some residue theorem from number theory)

It sound like an interesting problem, I will see if I can come up with something we I got some spare time. Sorry, can not type Chinese in office

不懂，但是帮你助威
