A uniform solid disk with radius 10 cm has mass 0.6 kg (moment of inertia I = ½MR2). A constant force 12 N is applied as shown. At the instant shown, the angular velocity of the disk is 30 radians/s in the −z direction (where +x is to the right, +y is up, and +z is out of the page, toward you). The length of the string d is 19 cm. At this instant, what are the magnitude and direction of the angular momentum about the center of the disk?
