Explanation / Answer

Here, Mg * sin(theta) * D =   1/2 * I * w2 + 1/2 * M * v2

=>   Mg * sin(theta) * D =   1/2 * (2/5 * M * R2) * w2 + 1/2 * M * (Rw)2

=>   g * sin(theta) * D =   1/2 * (2/5 * R2) * w2 + 1/2 * (Rw)2

=>     w = sqrt[(10g * sin(theta) * D)/7R2)]             --------------> angular velocity
