Question: separate what is their velocity at this instant 13 1342...

Question details

separate. What is their velocity at this instant? 13 13-42. Block A has a mass ma and is attached to a sprin;g having a stiffness k and unstretched length lo. 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 2Hag(mA + mB) /k, where μk 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? W A Probs. 13-41/42
