Using an electric motor, we accelerate a flywheel of rotationalmoment of inertia 12.4kg m^2 from the rest to an angular speed of200 RPM (revs/min) A constant friction torgue of 26.0 NM retardsthe motion.
a. if the angular acceleration is 4.20 rads/s^2, what is theaverage torgue T in Nm The motor applies to the flywheel?
b. what is the final KE of rotation of the flywheel injoules?
c. what average power does our motor supply in watts?
