A constant torque of 20 N is exerted on a pivoted wheel for 10 seconds during which,the angular velocity of the wheel changes from zero to 100r.p.m.When the external torque is removed,it is stopped by friction ion 100s. Find(i) the moment of inertia of the wheel,(ii) the frictional torque,(iii) the revolutions made by the wheel in 110s.
