2. A block of mass 3.2 kg lying on an inclined plane is connected to a hanging rock of mass 3.2 kg by a very light cord passing over a pulley at the top of the inclined plane. Determine the acceleration of the block, given a coefficient of friction of 0.15 and an angle of elevation of the ramp of 25 degrees. (Consider the mass and friction of the pulley to be negligible).
