(a) Determine the acceleration of the center of mass of a uniform solid disk rolling down an incline making angle θ with the horizontal. (Use theta for θ and g in each of the following equations, as appropriate.)

ahoop =

adisk =

(b) What is the minimum coefficient of friction required to maintain pure rolling motion for the disk?

Coefficient of friction =

Thanks in advance.
