Problem

A cord is wound around the rim of a solid cylinder of mass

10\,\text{kg}

and radius

0.2\,\text{m}

. The cylinder is mounted on a frictionless horizontal axle. A mass of

2\,\text{kg}

is suspended from the free end of the cord. Find the linear acceleration of the falling mass. Take

g = 10\,\text{m/s}^{2}
