Consider a motor that exerts a constant torque of 25.0 N⋅m to a horizontal platform whose moment of inertia is 50.0 kg⋅m2. Assume that the platform is initially at rest and the torque is applied for 12.0 rotations. Neglect friction. A. How much work W does the motor do on the platform during this process? 1885 J B. What is the rotational kinetic energy of the platform Krot,f at the end of the process described above? 1885 J C. What is the angular velocity ωf of the platform at the end of this process? Enter your answer in radians per second to three significant figures.
