A uniform circular disc of moment of inertia 0.2 kgm^2 and radius 0.15m is mounted on a horizontal cylindrical axle of radius 0.015m and negligible mass. Neglecting frictional loses in the bearing calculate, the angular velocity acquired from rest by the application for 24 seconds of a force of 20N tangential to the axle​
