Consider a motor that exerts a constant torque of 25.0 N cdot m to a horizontal platform whose moment of inertia is 50.0 kg cdot m^2. Assume that the platform is initially at rest and the torque is applied for 12.0 rotations. Neglect friction.What is the rotational kinetic energy of the platform K_rot,f at the end of the process described above?
