    A massless string is wrapped around a uniform solid cylinder with mass M = 10 kg and radius R = 0.40 m. One end of the string is attached to the cylinder and the free end is pulled tangentially by a force that maintains a constant tension T = 5 N . Find

    (a) the angular acceleration

    (b) the angular speed of the cylinder 5.0 s after the force is applied to the cylinder initially at rest.
