    A scientist builds a device to measure the speed of a golf ball. The 0.030kg ball is fired into a 0.080kg box that is attached to the edge of a record turntable (mass=0.050kg and radius=0.20m). As a result, the turntable spins. If the golf ball comes in with a speed of 26.0m/s, calculate the angular velocity of the turntable after the ball is caught.
