Two blocks, of weights 2.8 N and 5.5 N, are connected by a massless string and slide down a 47° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.087; that between the heavier block and the plane is 0.39. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.
