The large disk-shaped flywheel illustrated below has a radius R of 0.25 m. It is made to spin by the small wheel that contacts it at its rim. The small wheel applies a constant force of 945 N. Friction in the bearing exerts a ing torque 21 Nm on the large wheel.
If the magnitude of the angular acceleration of the large wheel is 63 rad/s2, what is its mass?
