The truck carries the spool which has a weight of 200 lb and a radius of gyration of k_G = 2 ft. Determine the angular acceleration of the spool if it is not tied down on the truck and the truck begins to accelerate at 5 ft/s². The coefficients of static and kinetic friction between the spool and the truck bed are respectively.
