The belt shown moves over two pulleys without slipping. Pulley A starts from rest with a clockwise angular acceleration defined by the relation α = 120 ?? 0.002ω2, where α is expressed in rad/s2 and ω is expressed in rad/s. Determine, after one-half revolution of pulley A,

(a) The magnitude of the acceleration of point B on the belt,

(b) The acceleration of point P on pulley C.
