text: If you can answer (a) the rest should be easy. You can define an "effective mass" Me as the sum of the mass and inertia/r^2. This is the mass that is accelerated by m*g. Then a=m*g/Me. This can be checked by computing the forces needed for the translational and rotational accelerations; their sum should equal m*g:\nf1=m*a\nang.accel=a/r\ntorque=ang.accel*I\nf2=torque/r\nf=f1+f2 \nMy result was I=0.000095 kg-m^2, Me=9.3973 kg, a=0.12523 m/s^2. \nChecking, f1=0.015027, f2=1.1618, f1+f2=m*g=1.1768
