例如图1所示,质量为m的物块,在平行斜面向上的恒力F的作用下,以初速度v0从底端加速到达顶端时的速度为v.若斜面长为L,高为h,与物块间的动摩擦因数为μ,求此过程中恒力所做的功.图2一、利用功能原理求解解如图2所示,首先对物块进行受力分析,设斜面倾角为θ,分解重力有G2=mgcosθ For example, as shown in Fig. 1, the mass m has a velocity of v at the initial velocity v0 from the bottom acceleration to the top under the action of a constant force F parallel to the oblique surface, and if the length of the slope is L, the height is h. The dynamic friction coefficient between the block and the block is μ. Find the work done by the constant force in this process. Fig. 2 1. Solving the solution by using the principle of function As shown in Fig. 2, the block is first subjected to force analysis, and the slope angle is set to θ, decomposition gravity with G2 = mgcosθ
