A solid cylinder of mass 12.0 kg and radius 0.250 m is free torotate without friction around its central axis. If you do 75.0 J of workon the cylinder to increase its angular speed, what will be its final angularspeed if the cylinder (a) starts from rest; (b) is initially rotating at12.0 rad/s?

Question

A solid cylinder of mass 12.0 kg and radius 0.250 m is free to
rotate without friction around its central axis. If you do 75.0 J of work
on the cylinder to increase its angular speed, what will be its final angular
speed if the cylinder (a) starts from rest; (b) is initially rotating at
12.0 rad/s?
