A ball of mass m = 5 kg moves freely in space: the velocity vc of the center C of the ball is 4 m / s, and its angular velocity? The rotation around the instantaneous axis Cz is 10 rad / s. Determine the kinetic energy of the ball if its moment of inertia relative to the Cz axis is 0.5 kg • m2. (Answer 65)
