Engineering Mechanics - Dynamics Chapter 13 Since a A a B = a = a kd x () m A m B + μ k g = N km B dx m A m B + = N = 0, then x = d for separation. At the moment of separation: 0 v v v d 0 d x m A m B + k g d = v kd 2 2 k gm A m B + d m A m B + = Require v > 0, so that 2 2 k A m B + d 0 > d 2 k g k m A m B + > Q.E.D Problem 13-51 The block A has mass m A and rests on the pan B , which has mass m B Both are supported by a spring having a stiffness k that is attached to the bottom of the pan and to the ground. Determine the distance d the pan should be pushed down from the equilibrium position and then
