Solving a problem in physics section 48 point 10 mechan

10. The man standing on the bench Zhukovsky, holding a rod of length l = 2,5 m and a mass m = 8 kg positioned vertically along the axis of rotation of the bench. This system (the bench and a person) has a moment of inertia J = 10 kg • m2 and rotates with a frequency n1 = 12 min-1. Determine the frequency n2 rotation system, if the rod is rotated to a horizontal position.
