A tight rope walker traverses a wire with the aid of a balancing pole. The moment of inertia of the person about their COG (Iperson) is 15 kg m^2. The moment of inertia of the pole about its COG (Ipole) is 250 kg m^2. As the person falls to one side, the pole imparts a CW restoring torque of ‐40 Nm on the person. What is the angular acceleration of the pole?
a. 0.16 rad/s^2
b. 2.67 rad/s^2
c. ‐2.67 rad/s^2
d. ‐0.16 rad/s^2
