13.7.2
A ball M of mass m = 0.2 kg moves with velocity v = 19.62 m / s relative to the vertical tube, which is attached to the vertical shaft 1 at a distance l = 0.5 m. The shaft rotates at a constant angular velocity ω = 5 rad / from. Determine the portable force of inertia of the ball. (Answer 2.5)
