Aflywheel in the form of a heavy circular disk of diameter 0.612 m and mass 301 kg is mounted on a frictionless bearing. a motor connected to the flywheel accelerates it from rest to 1060 rev/min. a) what is the moment of inertia of the flywheel? answer in units of kg · m2 .b)how much work is done on it during this acceleration? answer in units of j. c)after 1060 rev/min is achieved, the motor is disengaged. a friction brake is used to slow the rotational rate to 502 rev/min. what is the magnitude of the energy dissipated as heat from the friction brake? answer in units of j.
