The trailer has a mass of 580 kg and a mass center at G. The spool has a mass of 200 kg with a mass center at O and a radius of gyration about an axis passing through 0 and 0.45 m. If a force of 60 N is applied to the cable, determine the angular acceleration of the spool and the acceleration of the trailer. The wheels have negligible mass and are free to rotate.
