A 75-kg block is attached to a cable. The cable is then attached to a rotating assembly with a mass moment of inertia of 18 kg-m^2. The bearing friction applied at the rotating assembly equivalent to a couple of 45 N-m CCW. The block's downward speed is initially at 2 m/s. What is the total work done by the system after the rotating assembly has rotated 1.5 radians CW? What is the speed of the 75-kg block after the rotating assembly rotated 1.5 rad CW?
