A flywheel with Moment of Inertia I = 0.15 kg m 2 is rotating with 1000 rpm (revolutions/min) . The angular velocity can be calculated as
ω = (1000 revolutions /min) (0.01667 min/s) (2 π rad/ revolution )
= 104 rad/s
The flywheel kinetic energy can be calculated
E r = 1/2 (0.15 kg m 2 ) (104 rad/s) 2
= 821 J
