## Questions 11-12 A wheel with rotational inertia

I

is mounted on a fixed, frictionless axle. The angular speed

\omega

of the wheel is increased from zero to

\omega_{f}

in a time interval T. 11. What is the average net torque on the wheel during this time interval? (A)

\frac{\omega_{f}}{T}

(B)

\frac{\omega_{f}}{T^{2}}

(C)

\frac{I \omega_{f}^{2}}{T}

(D)

\frac{I \omega_{f}}{T^{2}}

(E)

\frac{I \omega_{f}}{T}

(A)
