## Homework Statement

## Homework Equations

All the usually relevant circular motion equations involving θ, I, ⍺, τ and ω

## The Attempt at a Solution

I've tried to work from the energy of the cylinder (Using Ek = Ktrans + Krot) and equating the energy to its potential energy at the point it starts to roll down but got nowhere near the answer. I've done the force diagram, which had the weight force, normal force and friction. For c), I think I'm supposed to use τ = r x F and F is the friction force. But I'm not sure whether to just use linear acceleration formulae to obtain acm.

Any help is welcome!
