Bucket A and block C are connected by a cable that passes over drum B. Knowing that drum B rotates slowly counterclockwise and that the coefficients of friction at all surfaces are µs =0.35 and µk = 0.25, determine the smallest combined mass m of the bucket and its contents for which block C will
(a) remain at rest,
(b) start moving up the incline,
(c) continue moving up the incline at a constant speed.
