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.
part a
how much work w does the motor do on the platform during this process?
part b
what is the rotational kinetic energy of the platform krot, f at the end of the process described above?
