Two solid uniform flywheels each of mass 650 kg and radius, Ask an Expert

Academics

Two solid, uniform flywheels, each of mass 65.0 kg and radius 1.47 m, rotate independently around a common axis. The first flywheel rotates in one direction at 20.84 rad/s; the other rotates in the opposite direction at 65.32 rad/s. Calculate the magnitude of the net angular momentum of the system.
