Calculating Angular Acceleration of a Rolling Drum on a Slope

[tronter]

A drum of radius $$R$$ rolls down a slope without slipping. Its axis has acceleration $$a$$ parallel to the slope. What is the drum's angular acceleration $$\alpha$$?

So $$v = R \omega$$ and $$a = R \alpha$$.So is it just $$\alpha = \frac{a}{R}$$?

Yep.

This is an old question that was previously answered here:
