A solid cylinder of mass 10 kg and radius 50 cm rotates with angular speed of 375 revs per minute. An object is then brought in contact with the cylinder while rotation causing a tangential force of friction of 2.0N
a) what is the angular acceleration of cylinder.
b) How long does it take for the cylinder to stop.
