A skater has rotational inertia 5.31 kg m² with his arms outstretched and a baseball glove on each hand; the pocket of each glove is 123 cm from his rotation axis. He's spinning with angular velocity pointing upward and with magnitude 0.950 rev/s. He catches a 146-g baseball moving at 19.7 m/s perpendicular to his arms and heading straight toward the pocket of his glove.
