Rotational motion is all around us

Find the tangential speed , tangential acceleration at, and centripetal acceleration ac of the point when the disk is rotating at a constant angular speed of 300 rev/min. Practice Problem 9 – 4: Find the linear speed of a point on the CD in Example 9 – 1 at (a) r = 2.40 cm, when the disk rotates at 500 rev/min, and (b) r = 6.00 cm, when the ... ................
