A ring of mass 0.2 kg is placed at the top of an inclined plane with angle 0 = 30°. The ring has radius 10 cm and rolls from rest without slipping. The coefficient of kinetic friction is 0.2. Given that the rotational inertia of a ring is MR², calculate Ring R = 10 cm M = 0.2 kg 0 = 30° (a) the magnitude of friction between the ring and plane. (b) the magnitude of torque applied on the ring. (c) the magnitude of angular acceleration of the ring. (d) the magnitude of angular momentum after 2 s. (e) the kinetic energy after 2 s.
