A box of mass m is on an incline with = 30°. It is connected to a massless rope and frictionless pulley where another box of mass M is suspended as shown. There is friction between the incline and mass m: the co-efficient of static friction is and the co-efficient of kinetic friction is 3√3. (a) Draw a free-body diagram for each box. √3 m |M| (b) Suppose the box on the incline is not moving, what is the maximum mass the hanging box M could be? What would this be in the case of no friction?
