A hollow sphereical shell rolls without slipping down a 38 degree slope, mass 2kg, find the acceleration the friction force and the minimum coefficent of friction needed to prevent slipping

2. Relevant equations

mgh, E=1/2mv^2=1/2Iw^2

3. The attempt at a solution

i dont really know where to start, i know moment of inertia will affect how fast this will accelerate due to gravity but im not given it so i dont know to solve it, hints would be great please!
