[1 point, 10 tries] A potter's wheel—a thick stone disk with a radius of 0.515 m and a mass of 107 kg—is freely rotating at 49.0 rev/min. The potter can stop the wheel in 5.10 s by pressing a wet rag against the rim and exerting a radially inward force of 69.9 N. Calculate the effective coefficient of kinetic friction between the wheel and the rag. Answer: 3.97E-01 2. 2 . [1 point, 10 tries] A cylindrical fishing reel has a moment of inertia of I=6.36×10 -4 kg·m 2 and a radius of 3.30 cm. A friction clutch in the reel exerts a restraining torque of 1.21 N·m if a fish pulls
