3. The wheel has weight 30 lb and radius of gyration about mass center is 0.5 ft. If it is subjected to couple moment of 10 lb-ft and rolls from rest without slipping, determine its angular velocity after mass center G moves 0.6 ft. The spring has a stiffness of k-15 lb/ft and initially unstreteched. (10 points) (Show FBD and Kinetic diagram) -K=161fx 0.7ft 101b-ft
