A high-speed sander has a disk 5.70 cm in radius that rotates about its axis at a constant rate of 1120 revolutions per minute.
a.) Determine the angular speed of the disk in radians per second.
b.) Determine the linear speed of a point 2.40 cm from the disk's center.
c.) Determine the centripetal acceleration of a point on the rim.
d.) Determine the total distance traveled by a point on the rim in 2.40 s.
