Blocks A and B are connected by a pulley system. The coefficient of kinetic friction between the block A and the incline is μk= 0.25, and static friction is insufficient to prevent slipping. The mass of A is mA = 7 kg, the mass of B is mB = 20kg, and the angle between the incline and the horizontal is θ = 30°. Determine the acceleration of A, the acceleration of B, and the tension in the rope after the system is released.
