A 1.25 kg hockey puck slides on a horizontal, frictionless surface at 3.0 m/s when it is struck by a 0.050 kg bullet traveling perpendicularly to the puck at 180 m/s. The bullet becomes wedged inside the puck. The sketch shows the view from above. After the collision, the speed of the composite puck/bullet object is_m/s. O A
