2. Consider a system shown in the figure. Block A weighs 45 N and block B weighs 25 N. Once block B is set into downward motion, it descends at a constant speed. a. Calculate the coefficient of kinetic friction between block A and the tabletop. b. A cat, also of weight 45 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)?
