Two blocks of masses m A 1.2 kg and mp 4.5 kg can slide one relative to one another, depending on the magnitude of the applied force P. The coefficient of friction between blocks A and B as well as between block B and the horizontal surface is 0.25. Case a: assume that the system is just on the verge of motion due to force P and calculate: • The frictional force FA/B = between A and...
