3. Two blocks with masses mi and m2 are connected by a mmssless string over a frictionless pulley. Block I sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle g above the horizontal. The coefficient of friction between block 2 and the incline is "k. The pulley, which is a uniform disk, has a mass mp and a radiws R. When release the blocks, both blocks slide without the string slipping on the pulley. In terms of the given parameters and physical constants, what is the speed of the blocks after the blocks have moved a distance of
