Statement of a problem № 41388


The inclined plane of Fig. forms an angle α = 30° with the horizontal. The mass ratio m2/m1 = η = 2/3. The coefficient of friction between the body m1 and the inclined plane is equal to k = 0.10. The masses of the pulley and the threads are negligible. Find the magnitude and the direction of acceleration of the body m2 when the formerly stationary system of masses starts moving.
