A cord of negligible mass is wound round the rim of a flywheel of mass 20 kg and radius 20 cm. A steady pull of 25 N is applied on the cord. The flywheel is mounted on a horizontal axis with frictionless bearings Find the kinetic energy of the wheel at this point when 2m of the cord is unwound. Assume that wheel starts from rest.

A cord of negligible mass is wound round the rim of a flywheel of mass 20 kg and radius 20 cm . A steady pull of 25 N is applied on the cord as shown in Fig. The flywheel is mounted on a horizontal axle with frictionless bearings. (a) Compute the angular acceleration of the wheel. (b) Find the work done by the pull, when 2 m of the cord is unwound. (c) Find also the kinetic energy of the wheel at this point. Assume that the wheel stars from rest. (d) Compare answers to parts (b)and (c).
