A certain non-uniform but cylindrically symmetric cylinder has mass 7 kg, radius 1.7 m, and moment of inertia about the center of mass 7.5 kg m2. It rolls without slipping down a rough 20° incline.

a) What is the acceleration of the cylinder's center-of-mass?
acm = m/s2

b) What minimum coefficient of friction is required so that there is no slipping?
µmin =

c) What is the ratio of kinetic energy about the center-of-mass to kinetic energy of the center-of-mass?
KErot/KEtrans =

d) Starting from rest, the cylinder rolls without slipping a distance d = 3.5 m down the incline. What is the final speed?
vf = m/s
