Homework Equations

Tangent Acceleration, Linear Acceleration

The Attempt at a Solution

I tried to made a free body diagram but i got confused with the inclined plane I am stuck there. Also with the Formulas for the accelerations...

PLEASE SOMEONE HELP ME!

ok I've been thinking about this and i think it might be two questions in one.

first, to analyze the linear motion of the center of the circle G. i would just treat the center as a particle, and use F=ma. draw out your FBD, use that 5-12-13 triangle instead of trig functions but in the same manner, that should get you the linear acceleration.

the second part is where i am getting confused. does the center of a circle have a angular acceleration? because the first derivation of angular acceleration would be displacement, S=(theta)(radius), but here radius is equal to zero, and therefore we have no S and therefore, no angular acceleration...


just an idea...
