The specifications for a ceiling fan you have just bought indicate that the total moment of inertia of its blades is 0.19 kg· m and they experience a net torque of 3.6 N. m. (a) What is the angular acceleration of the blades in rad/s?7 rad/s2 (b) When the blades rotate at 245 rpm, what is the rotational kinetic energy, in joules?
