A flywheel of mass M-3.0 kg and radius R-1.5 m rotates without friction at an angular velocity - 120 rpm on a frictionless, vertical shaft of negligible rotational Inertia. A second flywheel of mass M2-6.7 kg, which is at rest and has the same radus as the rotating flywheel, is dropped onto R (Figure below). Because friction exists between the surfaces, the flywheels very quickly reach the same rotational velocity, after which they spin together. Calculate the common angular velocity (in rpm) of the two flywheels. Treat the flywheels as solid disks. Round off your answer to a whole number but do not write the unit Second flywheel First flywheel

A flywheel of mass M-3.0 kg and radius R-1.5 m rotates without friction at an angular velocity we 120 rpm on a frictionless, vertical shaft of negligible rotational
Inertia. A second flywheel of mass M2- 6.7 kg, which is at rest and has the same radius as the rotating flywheel, is dropped onto it (Figure below). Because friction exists
between the surfaces, the flywheels very quickly reach the same rotational velocity, after which they spin together. Calculate the common angular velocity (in rpm) of the
two flywheels. Treat the flywheels as solid disks. Round off your answer to a whole number but do not write the unit.
