原题:图1所示为一根竖直悬挂的不可伸长的轻绳,下端拴一小物块A,上端固定在C点且与一能测量绳的拉力的测力传感器相连。已知有一质量为m0的子弹B沿水平方向以速度v0射入A内(未穿透),接着两者一起绕C点在竖直面内做圆周运
The original title: Figure 1 shows a vertically suspended inextensible light rope with a small block A at the lower end, with the upper end fixed at point C and connected to a load cell that can measure the tension of the rope. It is known that a bullet B with a mass of m0 is injected into A (not penetrated) at a velocity v0 in the horizontal direction, and then the two are circumferentially transported in a vertical plane around point C.
