A flywheel 0.800 m in diameter pivots on ahorizontal axis. A rope is wrapped around the outside of theflywheel, and a steady pull of 75.0 N isexerted on the rope. The flywheel starts from rest, and6.00 m of rope are unwound in 2.00 s.
(a) What is the angular acceleration of theflywheel?
rad/s2
(b) What is its final angular speed?
rad/s
(c) What is its final kinetic energy?
J
(d) What is its moment of inertia about the rotation axis?
kg·m2
