Consider a uniform disc in the x - y plane free to rotate about an axis parallel to the Z - axis as shown (passing through the centre). A force of 4N appliled at (4, 3) along y - axis, as shown produces an angular acceleration of `2s^(-1)`. Locate the centre of mass of the disc if the mass of the disc is 2 kg.
