關(guān)于彈簧簡諧運(yùn)動(dòng)的物理問題.怎么在碰撞后求振幅?
翻譯見下
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?
大概就是一個(gè)2kg的物體連在一端固定的水平彈簧上,沿x軸運(yùn)動(dòng),k＝100 無阻力.突然撞上一個(gè)沿x軸以3m／s 運(yùn)動(dòng)的2kg的小物塊.這兩個(gè)物塊粘在一起運(yùn)動(dòng),問周期和振幅.
周期求出來了是1.26,
