The force F, is applied to a rope which wraps around a hip with a radius of 200 mm. The disk has a mass of 30 kg. The disk moves in a vertical plane and has a radius of gyration of mass of 0.5 m with respect to a horizontal axis through the mass centre perpendicular to the plane of motion. The magnitude of the force F, in newtons is given by the ex- pression F, = 100+ 30^2, where t is in seconds. The sys- tem is released from rest when t is zero. When t = 4 s, determine (a) The angular velocity of the disk. (b) The velocity of point A on the rope.

3) The force F, is applied to a rope which wraps around a hip with a radius of 200 mm. The disk has a mass of 30 kg. The disk moves in a vertical plane and has a radius of gyration of mass of 0.5 m with respect to a horizontal axis through the mass centre perpendicular to the plane of motion. The magnitude of the force F, in newtons is given by the ex- pression F, = 100+ 30^2, where t is in seconds. The sys- tem is released from rest when t is zero. When t = 4 s, determine
(a) The angular velocity of the disk.
(b) The velocity of point A on the rope.
