Follow-up Question

Hello, I like the way you solve. Can you also answer this one? Thank you!

The 6 kg multiple pulley disc is configured as shown for an experiment. The disk is
unbalanced with a radius of gyration kg = 50 cm about its mass center G and
experiences a resisting torque of 0.3 Nm at pin C. Block A (mA= 0.845 kg) hangs off
a rope wrapped around the 250 mm pulley on the right side. If the system is
released from rest, (a) what is the angular acceleration of the disk in rad/s²? (b)
Find the tension in the rope in Newtons. (c) You are tasked with doubling the
acceleration solved in (a) by hanging another block off the 150 mm pulley.
Determine the mass of the block in kg necessary to achieve this. Indicate which
side of the 150 mm pulley you should hang the second block form. Include free
body diagram in every step and provide some explanations.
