如图1所示,设有长为s的水平传送带和质量为m的物体,物体与传送带间动摩擦因数为μ.下面,分五种情况讨论物体在传送带上的运动.
As shown in Figure 1, there is a horizontal conveyor belt of length s and an object of mass m. The dynamic friction coefficient between the object and the conveyor belt is μ. Below, the movement of the object on the conveyor belt is discussed in five different situations.
