Question1

One 2.9 kg paint bucket is hanging by a massless cord from another 2.9 kg paint bucket, also hanging by a massless cord.

(a) If buckets are at rest, what is the tension in each cord (lower and upper)?

(b) If two buckets are pulled upward with an acceleration of 1.90 m/s2 by the upper cord, compute the tension in each cord (lower and upper)?

Question2

A potter's wheel having a radius 0.55 m and a moment of inertia 10 kg m2 is rotating freely at 45 rev/min. The potter can stop the wheel in 6.5 s by pressing a wet rag against the rim and exerting a radially inward force of 65 N. Find out an effective coefficient of kinetic friction between wheel and the wet rag.
