Question 9 A uniform 4 kg solid disk of radius R = 1 mis free to rotate on a frictionless horizontal ande through its center. The disk is initially at rest, and then a 20 g bullet traveling at 300 m/s is fired into it as shown in Figure.If the bullet embeds itself in the disk at a vertical distance of 0.5m above the axle, what will be the angular velocity of the disk? V A. w=10 rad/s B. w=100 rad/s C. w= 1.5 rad/s D. W= 7.0 rad/s
