3. Consider the system shown in figure. Block A weighs 45.0 N and block B weighs 25.0 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 45.0 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)? -2.13 m/s^2 -4.56 m/s^2 -6.78 m/s^2 O -8.45 m/s^2 O No Answer A P
