Question: Block A has a mass m A and is attached to a spring having a stiffness k and unstretched length l 0 . If another

Block A has a mass m_A and is attached to a spring having a stiffness k and unstretched length l₀. If another block B, having a mass m_B is pressed against A so that the spring deforms a distance d, show that for separation to occur it is necessary that d > 2μ_k g(m_A+m_B)/k, where μ_k is the coefficient of kinetic friction between the blocks and the ground. Also, what is the distance the blocks slide on the surface before they separate? wwwwwwwww A B
