1. The problem statement, all variables and given/known data A wheel with rotational inertia I is mounted on a fixed motionless axle. The singular speed w of the wheel is increased from 0 to Wf in a time interval T. Net torque=IWf/T What is the average power input to the wheel during this time interval? 2. Relevant equations P=torque*angular velocity 3. The attempt at a solution P=(IWf/T)*Wf=(IWf^2/T) This isn't right though, what am I doing wrong?
