A flywheel is essentially a solid disk. Consider a flywheel with amass of 15.0 kg and a
diameter of 0.300 meters. An engine connected to the flywheelbrings the flywheel from 10.0 revolutions/second to 16.0revolutions/second in 8.00 seconds.
a) Calculate the flywheelâs angular acceleration.
b) Calculate the torque applied to the flywheel by theengine.
c) Calculate the diskâs angular displacement during the 8.00seconds it was accelerating.
d) Calculate the work done by the engine.
