题目如图1所示,许多工厂的流水线上安装有传送带,用传送带传送工件,可以大大提高工作效率.传送带以恒定的速率v=2m/s运送质量为m=0.5 kg的工件,工件从A位置放到传送带上,它的初速度忽略不计.工件与传送带间的动摩擦因数μ=
The problem is shown in Figure 1. Many factories have conveyor belts installed on the assembly line to convey workpieces using conveyor belts, which can greatly increase work efficiency. The conveyor belt conveys workpieces with a constant rate of v = 2m/s and masses of m = 0.5 kg. Placed on the conveyor belt, its initial velocity is ignored. The dynamic friction coefficient between the workpiece and the conveyor belt is μ =
