Question

A potter's wheel having a radius 0.55 m and a moment of inertia of 10.3 kg · m2 is rotating freely at 46 rev/min. the potter can stop the wheel in 6.0 s by pressing a wet rag against the rim and exerting a radially inward force of 66 n. find the effective coefficient of kinetic friction between the wheel and the wet rag.

Answer 1

The question asks for the calculation of the effective coefficient of kinetic friction, using principles of rotational motion in physics, for a potter's wheel scenario.

Step-by-step explanation:

The subject of the question is Physics, specifically revolving around the concepts of rotational motion, moments of inertia, angular velocity, and friction. The scenario presented involves a potter's wheel and the application of a force to alter its motion, which is a common example in physical mechanics. The problem requires the application of Newton's laws of motion in a rotational context as well as an understanding of the physical definitions and formulas for torque, moment of inertia, and friction.
