A block of 50 kg is attached to a cable. The cable is then attached to a rotating assembly with a mass moment of inertia of 10 kg-m^2. The bearing friction applied at the rotating assembly is equivalent to a couple of 50 N-m CCW. The block's initial downward speed is 1 m/s. 0.5 m 50 kg 3. Which of the following is closest to the work done by the weight of the 50-kg block after the rotating assembly has rotated 0.8 radians CW?
