A disk of radius 217 cm rotates about its axis. Points on the disk\'s rim undergo tangential acceleration of magnitude 2.31 m/s2. At a particular time the rim has a tangential speed of 1.05 m/s. At a time 0.833 seconds later, what is the tangential speed, v, of a point on the rim, the magnitude of the point's radial acceleration, and the magnitude of its total acceleration?
