3. In the figure below, two blocks are connected over a pulley. The mass of block A is 22 kg, and the coefficient of kinetic friction between A and the incline is 4, 0.28. The mass of block B is 18 kg. Angle is 30°. The system is prepared at rest but it starts moving as soon as it is released. -> 150 Frictionless, massless pulley B Assume that: The system is subject to the regular force of gravity. The connecting rope has negligible mass. The pulley has negligible mass (the pulley's function is only to redirect the rope.) (a) Determine whether block A is moving up or down the inclined plane. (b) Determine the acceleration of the system. (c) Find the tension on the rope.
