Afloor polisher has a rotating disk that has a 15-cm radius. the disk rotates at a constant angular velocity of 1.3 rev/s and is covered with a soft material that does the polishing. an operator holds the polisher in one place for 59 s, in order to buff an especially scuffed area of the floor. how far does a spot on the outer edge of the disk move during this time?
