2) Block B, with mass m3 = m: rests on block A: with mass mA 2 3m: which in turn is on a frictionless horizontal surface. Block A is attached to a spring of spring constant la. The coefcient of static friction between block A and B is p. The system is set into motion. a) What is the largest speed that the two block system can have during this motion if block B is not to slip at any time? b) The surface is now inclined to an angle that is 30\" to the horizontal. Now is the largest speed that the two block system can have during this motion if block B is not to slip at any time? c) Block B is lifted off of block A at the point of largest displacement from its equilibrium position as it oscillates without slipping on the inclined surface of b). What is the change in the amplitude of the oscillation
