Neglect the mass of the cord and pulleys. Problem 13-49 Block A has mass mA and is attached to a spring having a stiffness k and unstretched length l0. Determine the distance both blocks slide on the smooth surface before they begin to separate. What is their velocity at this instant? Problem 13-50 Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length l0. If another block B, having a mass mB is pressed against A so that the spring deforms a distance d, show that for separation to occur it is necessary that d > 2 k g(mA+mB)/k, where 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?
