一、题目如图,质量为m_1的物体经一轻质弹簧与地面上的质量为m_2的物体相连,弹簧的劲度系数为k,A、B都处于静止状态.一条不可伸长的轻绳绕过轻滑轮,一端连物体A,另一端连一轻挂钩.开始时各段绳都
The problem is shown in the figure. The object with mass m_1 is connected to an object with mass m2 on the ground via a lightweight spring. The stiffness coefficient of the spring is k, and both A and B are in a static state. An inextensible light rope Bypassing the light pulley, one end is connected to the object A and the other end is connected to a light hook.
