不等式中有一个不仅常见而且非常重要的不等式:均值不等式.具体公式:a,b∈R+,a+b≥2ab1/2,(当且仅当a=b时取等号).这个公式不仅在数学中非常重要,在物理中的应用也非常广泛.举两个例子说明.例1(2010年江苏理综第14题)在游乐节目中,选手需借助悬挂在高处的绳飞越到水面的浮台上,小明和小阳观看后对此进行了讨论.如图所示,他们将选手简化为质量m=60kg的质点,选手抓 In inequality, there is not only a common and very important inequality: mean inequality. The formula is: a, b∈R +, a + b≥2ab1 / 2, (if and only if a = b take equal sign.) This formula not only in Mathematics is very important, the application of physics is also very extensive .Considering two examples.Example 1 (Jiangsu Lihe 2010Sim14) In the amusement program, players need to rely on the suspension of the rope over the top to the surface of the water Floating on the stage, Xiao Ming and Xiao Yang after the discussion of this.As shown, they will simplify the players for the mass m = 60kg of the particle, the player caught
