A turbine is constructed such that is made of a 5.00 kg thick-walled cylinder of length 1.00 m, inner and outer diameter of 35 cm and 50 cm, respectively. Inside the hollow cylinder, four 1.00 kg thin rectangular plates of length 1.00 cm and width of 17.5 cm are connected from the rotation axis of the turbine, which is parallel to the length of the turbine and through the center of the cylinder. (a) Calculate the moment of inertia of the turbine about its rotation axis. The turbine is initially rotating when it is turned off by a constant torque of 0.41 mN and slowly rotates until it come to a full stop after 3.00s. (b) What is the angular acceleration of the turbine? (c) What was the rotational kinetic energy of the turbine at the instant it starts to decelerate?
