A 60-mm-radius drum is rigidly attached to a 100-mm-radius drum as shown. One of the drums rolls without sliding on the surface shown, and a cord is wound around the other drum. Knowing that end E of the cord is pulled to the left with a velocity of 120 mm/s, determine

(a) The angular velocity of the drums,

(b) The velocity of the center of the drums,

(c) The length of cord wound or unwound per second.
