A solid cylinder of mass 12.0 kgkg and radius 0.250 mm is free to rotate without friction around its central axis.
A) If you do 75.0 JJ of work on the cylinder to increase its angular speed, what will be its final angular speed if the cylinder starts from rest? Express your answer in radians per second.
B) What will be the cylinder's final angular speed if it is initially rotating at 12.0 rad/s?
