Mass Ma lies on top of mass Mp, as shown. Assume M, > Mạ. The two blocks are pulled from rest by a massless rope passing over a pulley. The pulley is accelerated at rate A. Block M, slides on the table without friction, but there is a constant friction force f between Ma and M, due to their relative motion. Find the tension in the rope.
