Block A rests on block B and it is connected to the wall by the weightless link "de". The masses of blocks A and B are ma 147[kg] and mb 222[kg], respectively. The coefficients of kinetic friction between surfaces A-B and B-C are µAB=0.1 and µBC=0.14, respectively. Find: a) The required magnitude of the horizontal force (P) acting on block B that will cause it to accelerate to the left at 2 m/s2. b) The corresponding value of the link force. (Hint: Block A does not move!) d 20 A (ma kg) B (mb kg) P C
