'A block of 50 kg is attached to a cable. The cable is then attached to a rotating assembly with mass moment of inertia 10 kg-m^2. The bearing friction applied at the rotating assembly equivalent to a couple of 50 N-m cCW is resisting the block's downward speed which is initially at 1 m/s. 0.5 m 50 kg
