Задача id13258

A block of mass m1, on which a second block of mass m2 is located, slides along an inclined plane with an angle of inclination a. The coefficient of friction between the lower block and the inclined plane is equal to k1, and the coefficient of friction between the bars is equal to k2, and k1 > k2. Determine whether the upper block will move relative to the lower one and what are the accelerations of both bars. How will the result change if k1 k2 tga?
