Hi,

I have the following problem that I'm lost on.

The answer is 41.4 rad/s

ƩT=I(alpha)

I=1/3 ML

I solved the above equations to get (alpha)=T/I, but no matter what I try from here I get small numbers under 5.

I'm confused on a couple points: is the center of gravity in the middle of the rod or the tip? Should I add the mass of the box (since the cable is cut, not the rope)? And I'm really confused as to how to write the sum of torques.

I tried following this example, with and without the box, but it I'm getting small numbers not even close to 41. Could someone please explain clearly to go about solving this? Thank you!
