Blocks A and B are connected by the pulley system shown. Friction between the block A and the incline is negligible. The weight of A is WA = 12 lb, the weight of B is WB = 30 lb, 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.
