A 2.8-kg 12-cm-radius cylinder, initially at rest, is free torotate about the axis of the cylinder. A rope of negligible mass iswrapped around it and pulled with a force of 15 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 = 0.70 s.
rad/s
