You are in a room in a basement with a smooth concrete floor (friction force equals 40 n) and a nice rug (friction force equals 55 n) that is 3 m by 4 m. however, you have to push a very heavy box from one corner of the rug to the opposite corner of the rug. will you do more work against friction going around the floor or across the rug, and how much extra?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
