问题1 两个质量分别为 m_1和 m_2的木块用劲度系数为k的理想弹簧连接(如图1),最初这个系统是平衡的.(a)如要使下面的木块跳离桌上面的木块须离开平衡位置的最小位移和方向如何
Problem 1 The two blocks of mass m_1 and m_2 are connected by an ideal spring with a stiffness factor of k (Figure 1). Initially the system is balanced. (a) If you want to make the following blocks jump off the table What is the minimum displacement and direction of the block from the equilibrium position?
