ABC bar has a mass of 2.87kg and is attached to a B-bracket bolt. A 0.65kg D-sphere hits the end of the bar with a vertical velocity v1 of 3.32m / s. If L = 0.73m and the coefficient of restitution between the sphere and the bar is 0.49, determine the angular velocity, in rad / s, of the bar immediately after impact.
