"In pure translation motion velocity of every particle of body at any instant" is what? Equal or unequal ?
Why does the internal forces acting on the centre of mass of the system be neglected ?
A cylinder of mass $M$ and radius $r$ is mounted on a frictionless axle over a well. A rope of negligible mass is wrapped around the cylinder and a bucket of mass $m$ is suspended from the rope. The linear acceleration of the bucket will be
