17N.3.SL.TZ0.7c

A hoop of mass m, radius r and moment of inertia mr2 rests on a rough plane inclined at an angle θ to the horizontal. It is released so that the hoop gains linear and angular acceleration by rolling, without slipping, down the plane.

(c)

Calculate the acceleration of the hoop when θ = 20°. Assume that the hoop continues to roll without slipping.
