1. The problem statement, all variables and given/known data A man (mass m1 = 100 kg) stands at the fringe of the large rotary table (radius R = 5 m, massm2 = 100 x m1), which rotates at a frequency of 10/min. The man goes along a radius line towards the table center until he reaches the rotation axis. The spatial extent of the man should be neglected. a) How does the rpm (revolutions per minute) number of the rotary table change (in absolute und relative terms)? b) The man has to work against the centrifugal force in order to get to the center of the table. Show that the work done by the man amounts to the increase of the rotational energy of theentire system. 2. Relevant equations conservation of momentum: p = p1 + p2 rotational energy : 1/2mr^2w^2 3. The attempt at a solution Period of 36s with man on edge. How is it different when he is in the middle?
