so T= 1/2 (M V^2) +1/2(I ω^2)

where M is the mass of the disk and V is the velocity of the CM and I is the moment of inertia of the disk and W is the angular velocity about the CM

am i wrong ?

why some books sole this problem for rotational kinetic energy only and ignore the term of kinetic energy that depends on the velocity of the center of mass with respect to the origin

in ohter words they consider T = 1/2 I ω^2 only :(
