A part of a mobile suspended from the ceiling of an airport terminal building consists of two metal spheres, the first sphere has a mass of 2.0 kg, and the second one is 3.0 Kg. They are connected by a uniform metal rod with a mass of 3.6 kg and a length of 4.0 m. The assembly is suspended at its midpoint by a wire and rotates in a horizontal plane, making 7.0 rpm. Find: A. The angular momentum of the system, B. The kinetic energy of the assembly, 2.0 kg 4.0 m C. Calculate the power consumption in 3 hours working. 7.0 rpm 3.6 kg 3.0 kg
