6. Consider the system shown in the figure. Block A weighs 45.0 N and block B weighs 25.ON. Once block B is set into downward motion, it descends at constant speed. a. Calculate the coefficient of kinetic friction between block A and the tabletop. b. A cat, also of weight 45.0 N, falls asleep on top of block A, If block B is now set to downward motion, what is the acceleration (magnitude and direction)?
