Two steel ball of equal diameter are connected by a rigid bar of negligible weight as shown and are dropped in the horizontal position from height `h` above the heavy steel and brass base plates. If the coefficient of restitition between the ball and steel base is `0.6` and the between the other ball and the brass base is `0.4`. The angular velocity of the bar immediately after rebound is. (Assume the two impacts are simultaneous). .
