在物理教师交流社的一次讨论中,一位教师提出了一个问题.原题.如图1所示,劲度系数k=100N/m的一根轻质弹簧,左端固定在竖直墙壁上,右端连接一质量为m=1kg的小物块,开始时弹簧处于原长,小物块静止于O点.现将小物块向右拉动至A点(未超弹簧弹性限度)后由静止释放,让小物块沿水平面向左运动起来.已知OA长L=0.25m,小物块与水平面
In a discussion at the Physics Teachers’ Exchange Society, a teacher raised a question, as shown in Figure 1. A lightweight spring with a stiffness factor k = 100 N / m was fixed to the vertical wall at the left end, The right end is connected to a mass of m = 1kg of small pieces, the beginning of the spring is in the original length, small pieces still at point O. Now pull the small piece to the right to point A (not exceeding the spring limit of elasticity) by the static release, so that small objects The block moves to the left along the horizontal plane, and it is known that the length of OA is L = 0.25m, with small blocks and horizontal plane
