Athin, uniform metal bar, 2.00 m long and weighing 90.0 n, is hanging vertically from the ceiling by a frictionless pivot. suddenly it is struck 1.50 m below the ceiling by a small 3.00-kg ball, initially traveling horizontally at 10.0 m/s. the ball rebounds in the opposite direction with a speed of 6.00 m/s. (a) find the angular speed of the bar just after the collision. (b) during the collision, why is the angular momentum conserved but not the linear momentum?
