tangential speed=radius*w
w=503rev/min(1min/60sec)(2PIrad/rev) to get into rad/sec
put radius into meters.
a high speed sander has a disk of 2.74 cm in radius that rotates its disks about the axis at a constant rate of 503 rev/min. determine the linear speed of a point 2.33 cm from the disk's center. answer in units of m/s
