A wheel with radius 0.33

A wheel with radius 0.33 m and rotational inertia 2.0 kg⋅m2 spins on an axle with an initial angular speed of 3.0 rad/s. Friction in the axle exerts a torque on the wheel, causing the wheel to stop after 6.0 s. The average torque exerted on the wheel as it slows down has magnitude

A) 0.50 N⋅m
B) 1.0 N⋅m
C) 2.0 N⋅m
D) 3.0 N⋅m


B) τ = 1.0 N•m
