Part A The system is released from rest at 0= 0° when a constant couple moment M = 100 N·m is applied. (Figure 1) If mass of the cable and links AB and BC can be neglected, and each pulley can be treated as a disk having a mass of 6 kg, determine the speed of the 20-kg block at the instant link AB has rotated 0-90°. Note that point C moves along the vertical guide. Also, the cable does not slip on the pulleys. Express your answer to three significant figures and include the appropriate units.
