Apottery wheel, initially at rest, is assumed to be a uniform disk of mass 3.0 kg and radius 20.0 cm. a 25.0 n force is applied tangentially to the rim.
(a) what is the angular acceleration of this pottery wheel?
(b) if the force is applied for 30.0 sec, find the instantaneous angular velocity at 30.0 sec.
(c) what will be the angular displacement for this wheel from t= 15 s until t= 30s?
