Consider the pulley system below in which a stack of blocks of mass m1 and m2 is being pulled bya string connected to a block of mass m3, draped over a pulley. Assume the mass of the pulley andthe friction in its bearing are negligible. The string is lightweight and does not stretch. Supposethat there is no friction between block 2 and the horizontal surface. However there is frictionbetween blocks 1 and 2 with coefficients of kinetic and static friction Hk and µs, respectively.m2m3Answer the following questions, following the problem-solving checklist as you present your work.1. Assume that the three masses are such that blocks 1 and 2 do not slide relative to each other.Given m1, m2, m3, µk, and µs, find the magnitude of the friction force between blocks 1 and 2.2. Given the friction coefficients and the masses of blocks 1 and 2, for which values of mass m3will blocks 1 and 2 slide on each other?3. Are there values of mị and m2 for which the two blocks will remain stuck together regardlessof the size of block 3?Something to think about (but not turn in): What if mass m2 is very, very big compared to theother blocks. In this case, do your answers to questions 1 and 2 make sense, physically?
