Question

Just after the cable becomes taut, which of the following absolute-relative velocity equations is VALID to relate end B and mass center O of disk O?

Chika Fujiwara loves to play games. Ever curious, she
observes that a uniform disk 0 (mass = 0.500 kg) of
radius 0.1500 m is falling freely with a velocity of 1.200
m/s and with no angular velocity when an inextensible
cord AB suddenly becomes taut. Assume that at the
instant just before the cord becomes taut, B is directly
to the left of O.
