Solving a problem in physics section 5 point 80 mechani

80. A man is standing on a bench Zhukovsky hand and catches the ball mass m = 0,4 kg flying horizontally with a speed υ = 20 m / s. The trajectory of the ball is at a distance r = 0,8 meters from the vertical axis of rotation of the bench. What is the angular velocity ω starts to rotate bench Zhukovsky with a person catches the ball, if the total moment of inertia J and the person bench is 6 kg • m2?
