A potter's wheel is 101 kg and has radius of 0.483 meters and is freely rotating at 71.9 rev/min. the potter can stop the wheel in 6.54 s by pressing against the rim and exerting a radially inward force of 103 N. find coefficient of kinetic friction.(adsbygoogle = window.adsbygoogle || []).push({});

I found alpha=71.9 x 2 x pi/60sec/ 6.54= 1.15 rad/s^2

Torque= I x alpha = 27.126

however, i don't know where to go from here. Thanks for any help.
