Okay. I set up my equation for translational motion to be ma=mgsin(theta) - (coefficient of friction)*mgcos(theta). So a=gsin(theta) - gcos(theta)*(coefficient of friction). Is that right? I don't understand how I can get acceleration from rotational motion.

Homework Statement A uniform solid sphere rolls down an incline without slipping. If the linear acceleration of the center of mass of the sphere is 0.22g, then what is the angle the incline makes with the horizontal? Homework Equations a=gsin(theta) The Attempt at a Solution The...

Thanks Doc Al, I just tried what you said and understood where I was going wrong. I wasn't separating the forces into 2 separate components, but rather tried solving with them together. After following your instructions, I got the answer right! Thanks for your help!

I'm having difficulty with this same question (although my Fo has an acceleration of 16m/s^2). I understand how to find the magnitude of the acceleration for diagram a, but still don't understand how to go about breaking into components of x and y for diagram b. Can anyone explain further...
