题目.如图1所示,劲度系数k=100N/m的一根轻质弹簧,右端固定在竖直墙壁上,左端连接一质量m=1.0kg的小物块.开始弹簧处于原长,小物块静止于O点.现将小物块缓慢向左拉动至A点释放,让小物块沿水平面向右运动起来.已知OA长度L=0.25m,小物块与水平面的动摩擦因数μ=0.1,最大静摩擦力可看成等于滑动摩擦力的大小,g取10m/s2,求小物块从A点开始运动直至静止的总路程.
Title as shown in Figure 1, a stiffness spring coefficient k = 100N / m a light spring, the right end fixed to the vertical wall, the left end connected to a mass m = 1.0kg small pieces. Start spring in the original length, small objects Block still at point O. Now the small block slowly pulled to the left A release, so that the small block along the horizontal plane to the right movement.Of known OA length L = 0.25m, small blocks and the horizontal dynamic friction coefficient μ = 0.1, the maximum Static friction can be regarded as equal to the size of sliding friction, g take 10m / s2, find a small block from point A until the total distance of motion.
