The figure shows the view looking down onto an air hockey table. A puck collides with a stationary bar. The collision is completely inelastic. The bar has mass M = 1.11 kilograms and length L = 1.36 meters. The puck has mass m = 0.444 kilograms and is initially moving at vi = 6.61 perpendicular to the bar. The puck collides with the bar at a location of b = 0.465 meters from the center of the bar. Note that the size of the puck is negligible compared to the length of the bar. Calculate the center of mass speed (in m/s) of the puck-and-bar system just after the collision. Calculate the angular speed (rad/s) about the center of mass of the puck-and-bar system just after the collision.
