Is Part C Right. I was suppose to fill in the blanks

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.

Which quantities are scalars? choose all that apply a.distance b.speed c. acceleration d.velocity
