A flywheel of mass 5kg and radius of gyration 0.5 rotates about its axis.find the kinetic energy of rotation of wheel if it makes 300 revolution per minute

The mass of flywheel [m] = 5 kg. Radius of gyration [R] = 0.5m The frequency of flywheel [f] = 300 rev/min. We have 1 min = 60 seconds.  Hence, 300 rev/min = 300/60 rev/sec   ...
