Need $100\%$ correct answer i will give thumbs up if wrong thump donw

Required information

Problem $16\mathrm{.}158-$ Centroidal rotation $-$ DEPENDENT MULTI$-$PART

PROBLEM $-$ ASSIGN ALL PARTS

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be

unable to return to this part.

The uniform rod AB of weight W is released from rest when beta$=72^($@$).$

Problem $16\mathrm{.}158.$a $-$ Centroidal rotation

Assuming that the friction force is zero between end A and the surface, determine the angular

acceleration of the rod immediately after release.

The angular acceleration of the rod is

ox$($g$)/($L$).$
