A particle of dust lands 41.4 mm from the center of a compact disc (CD) that is 120 mmin diameter. The CD speeds up from rest, and the dust particle is ejected when the CD is rotating at 82.0 revolutions per minute. What is the coefficient of static friction between the particle and the surface of the CD?
