(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A uniform sphere rolls down a 30 degree incline θ from height h. Initially, the solid is at rest. Find the acceleration for the center of the mass of the solid.

I am not sure where to start with this problem. I started with the energy formulas, but I am not sure how to find the acceleration of the center of mass from there. I just need a guide on what formulas or setup to use, thanks!

2. Relevant equations

Translational and rotational motion equations

3. The attempt at a solution

K_i=mghsin30

K_f=1/2mv^2+1/2Iω^2

then I solved for v:

v=radical(10/7*ghsin30)
