A 2.3-kg 10-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.
in N · m
(b) Find the angular acceleration of the cylinder.
in rad/s2
(c) Find the angular velocity of the cylinder at t = 1.40 s.
in rad/s
