Rotational Work-Energy Theorem
A flywheel of moment of inertia I, initially rotating with angular velocity ω₀, is brought to rest by a constant frictional torque, τf. If the flywheel rotates through an angular displacement of θ before stopping, what is the magnitude of τf?
A
Iω₀/θ
B
Iω₀²/(2θ)
C
Iω₀²θ/2
D
Iω₀²/θ
