A thin, uniform, metal bar, 2.00 m long and weighing 90.0 N, ishanging vertically from the ceiling by a frictionless pivot.Suddenly it is struck 1.50 m below the ceiling by a small 3.00-kgball, initially traveling horizontally at 10.0 m/s. The ballrebounds in the opposite direction with a speed of 6.00 m/s.
Part A) Find the angular speed of the bar just after the collision.
