The reel of cable has a mass of 400 kg and a radius of gyration of k

Question:

The reel of cable has a mass of 400 kg and a radius of gyration of k_A = 0.75 m. Determine its angular velocity when t = 2 s, starting from rest, if the force P = (20t² + 80) N is applied, where t is in seconds. Neglect the mass of the unwound cable, and assume it is always at a radius of 0.5 m.
