Question: If the horizontal surface is smooth, two 4 0 9 - mm diameter disks and a 1 4 7 - mm diameter disk are joined

If the horizontal surface is smooth, two 409-mm diameter disks and a 147-mm diameter disk are joined to form a spool. The
457-kg spool has a radius of gyration of 141-mm with respect to axis of the spool. If a force P of 273-N is applied to the spool
through a cord wrapped around the 147-mm disk, determine the angular acceleration of the spool.
If the horizontal surface is smooth, two 4 0 9 -
