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. A 30⁰ B r = 0.15 m
