A 3.0-kg 14-cm-radius cylinder, initially at rest, is free to rotate about the axis of the cylinder. A rope of negligible mass is wrapped around it and pulled with a force of 18 N.
a) Find the magnitude of the torque exerted by the rope.
b) Find the angular acceleration of the cylinder.
rad/s2
c) Find the angular velocity of the cylinder at t = 1.40 s.
rad/s
