While sitting in a swivel chair, you push against the floor with your heel to make the chair spin. The 6.7 N frictional force is applied at a point 39 cm from the chair's rotation axis, in the direction that causes the greatest angular acceleration.
If that angular acceleration is 1.8 rad/s², what is the total moment of inertia about the axis of you and the chair?
