sorry... you all were right about the moment of inertia. when the axis of rotation is located on the center of mass then the moments of inertia are the same. i did finally figure this problem out and will post the method for others learning purposes. D=given M=given g=given First, you...

that is true, but i am not given the MoI about the axis of rotation so then i am stuck.

yeah, i was given the moment of inertia about the center of mass, not the moment of inertia about the axis of rotation. which is I= I_cm + mr^2.

[SOLVED] help! where can i find mass? Homework Statement A spool of thin wire (with inner radius R=0.50m outer radius R=o.65m, and a moment of inertia I_cm=0.8957 kg*m^2) pivots on a shaft. The wire is pulled down by a mass M=1.5 kg. After falling a distance D=0.51m, starting from rest, the...
