A 2.1-kg 15-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 14 N.
(a) Find the magnitude of the torque exerted by the rope.
?N · m
(b) Find the angular acceleration of the cylinder.
?rad/s2
(c) Find the angular velocity of the cylinder at t = 1.00 s.
?rad/s
