If the elevator’s mass is 1,000 kg, and the counter weight’s mass is 850kg, what would be the system’s acceleration

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
