A 2.00-kg object is attached to an ideal massless horizontal spring of spring constant 100.0 N/m and is at rest on a frictionless horizontal table.The spring is aligned along the x-axis and is fixed to a peg in the table.Suddenly this mass is struck by another 2.00-kg object traveling along the x-axis at 3.00 m/s,and the two masses stick together.What are the amplitude and period of the oscillations that result from this collision?
大概就是一个2kg的物体连在一端固定的水平弹簧上,沿x轴运动,k＝100 无阻力.突然撞上一个沿x轴以3m／s 运动的2kg的小物块.这两个物块粘在一起运动,问周期和振幅.
周期求出来了是1.26,
答
首先要明题意：一个质量为 m=2kg的物体与一个水平的轻质弹簧连接,静止地放在表面光滑无摩擦的水平桌面上,弹簧的另一端固定.以弹簧的方向为x轴,另一个质量为m= 2.0kg的物块以3.0m/s的速度沿x轴的方向突然撞上跟弹簧连...
