The cable drum shown rolls on the ground surface without
slipping at a constant angular velocity of 69 rpm while cable is
pulled horizontally to the right. In case A the cable unwinds from
the top of the inner drum. In Case B the cable unwinds from the
bottom of the inner drum. Assume the inner and outer drum radii are
820 mm and 1312 mm, respectively. Determine (a) the velocity in m/s
of the cable in Case A, (b) the velocity in m/s of the cable in
Case B and (c) the velocity in m/s of the drum center.
